America's Got Talent

Matt Mauser -- who lost his wife in the helicopter crash that also killed Kobe and Gigi Bryant -- gave an emotional audition for "America's Got Talent" on Tuesday ... and the performance is incredibly moving.

The 51-year-old shared his tragic story with judges Simon Cowell, Heidi Klum, Sofia Vergara and Howie Mandel ... before singing a rendition of "Against All Odds" by Phil Collins.

Mauser -- who met Christina at a bar in 2004 -- broke down his final memories of his wife ... saying she kissed him goodbye and said "I love you" before the fatal helicopter ride in Jan. 2020.

Mauser got teared up before performing the cover ... as he brought his 3 children on stage.

Not only is his story powerful, but Mauser has some serious pipes ... giving it his all.

After completing the audition, Mauser got a standing ovation from the judges and the audience ... and there may not have been a dry eye in the house.

Mandel applauded Mauser for being able to move an entire room full of strangers ... with each judge giving him a resounding "yes" to move on to the next round.

Simon Cowell insists he's not living dangerously by getting back on an electric bicycle less than a year after shattering his spine while riding one ... 'cause he's toned down his horsepower.

The "America's Got Talent" judge and music exec broke down the differences for us after he was spotted scooting around on a new bike, but one that still had an electric motor attached.

It looks like risky business, but Simon explains he wasn't concerned. Check out why this new ride of his isn't anywhere near as crash-prone as the one he crashed with last summer.

The long and short of it is ... one of them was basically a motorcycle with pedals, and the other is a lot more human-friendly and manageable.

SC actually tells us a pretty hilarious anecdote about a magazine he picked up recently that served as a painful reminder of the brutal injury he endured.

Speaking of that injury ... Simon has healed very nicely since August, which was pretty obvious from his vacation to Barbados over the holidays -- where he was spotted cruising around on a jet ski, something he tells us his doctor did NOT want to see happen.

Tough luck for the doc -- Simon likes living on the edge, but at least he's taking a much wiser, sensible approach now.

Simon Cowell is getting back on the horse -- or, more accurately, back on the bike ... this after breaking his back on one of these damn things less than a year ago.

The 'AGT' host was spotted cruising along on another electric bicycle Sunday in Malibu with his girlfriend, Lauren Silverman, and his young son, Eric ... who all had bikes of their own. Interestingly, though, it was only Simon who seemed to be using a motorized version.

You can tell it's an electric bike by that little box stuck to the down tube of the frame -- they help propel the bicycle forward with more acceleration as you pedal, giving you a boost.

The fact Simon's once again riding one of these raises eyebrows at first glance. Of course, Simon practically shattered his spine on this exact type of model back in August ... when he was testing out a new electric bike of his, in none other than the courtyard of his own home.

If he almost got paralyzed from just that setting ... this one here -- out in public, along a windy bike bath with other riders zipping by -- is definitely a lot more dangerous, potentially. Still ... it looks like he's got the hang of it, but seeing this does make one worry a bit.

Simon went through a 6-hour emergency back surgery at the time ... and has undergone intensive rehab since then to get back on his feet. Welp, now he's back on his ass.

Grace VanderWaal isn't seeing stars, she's seeing dollar signs ... because we've learned she's getting paid a nice chunk of change for her lead role in "Stargirl."

The 17-year-old singer is off to a pretty strong start financially in her acting career after securing top billing in the Disney+ movie, "Stargirl." According to her minor's contract, obtained by TMZ, Grace took home a base salary of $125,000 for the first film, and it looks like she's got a bigger payday on the horizon for the upcoming sequel.

Grace is in line to double her earnings for the second 'Stargirl' movie ... the contract says she'll get paid a cool $250,000 to reprise her role as Stargirl Caraway, and Disney says the sequel is already in development.

We'll do the math for ya ... Grace will earn at least $375,000 just in base pay for both films. And, if there's a third film, she'll rake in $500,000. Yes, it pays well to be a Disney star.

A brother and sister who gained fame on "America's Got Talent" with their magic act probably wish they could have disappeared during a tense confrontation with cops ... because they got arrested for refusing to live with their mom.

The teenage siblings, Kadan and Brooklyn Rockett, were arrested last week in Farmerville, Louisiana after refusing to go with police who were trying to return them to their mother. A Missouri judge ordered the handoff in the ongoing custody battle with their father.

We're told the arrest stems from a 2019 Missouri court order requiring the kids to split their time with their mom and dad... and law enforcement sources tell us they had paperwork authorizing the handoff. Our sources say the kids have been living with their dad in California for years, but have refused to see their mom.

In the video, the teens say they're afraid of their mother and don't want to go back to her, but cops say they have no choice. The kids refuse to comply, so the cop begins reading them their Miranda rights and slaps the cuffs on 15-year-old Kadan. 13-year-old Brooklyn -- who's sobbing during the arrest -- was also cuffed.

Our sources say the siblings were in Louisiana for their grandmother's funeral, so that is how the mother knew where they would be in order to send the police to pick them up.

Law enforcement sources tell us the children were held at the Green Oaks Detention Center in Monroe overnight to await a court hearing the next morning.

It's unclear exactly what went down at the hearing because the judge ordered it to be sealed, but we're told Kadan and Brooklyn were released back to their father ... at least for now.

The Rockett parents have been divorced since 2009, but the nasty custody battle has been ongoing. There was a similar incident with the kids and a Missouri judge in October 2019.

We've reached out to the kids' mother ... so far, no word back.

Simon Cowell is still on the mend from his broken back -- and while he recovers, he decided to polish up his smile while he was at it ... TMZ has learned.

Sources tell us the music exec and 'AGT' host recently got a new set of pearly whites from Beverly Hills cosmetic dentist Dr. Apa, at his private practice. We're told Simon came in last month looking for the makeover, and just had new veneers installed this past weekend.

Turns out, Simon was actually in need of a new set -- we're told he was doing away with older, temporary veneers he'd been rockin' -- but had one request ... less Simpson-y and more streamlined. In other words, he wanted a thinner, more natural-looking smile ... and sources say he even had a pic of his OG teeth for reference on the updated design.

After two appointments at three hours a pop, we're told Simon walked away happy as can be -- and even posed with the doc on his way out. As for cost ... our sources tell us Dr. Apa usually charges around $4,000 per tooth. Considering Simon got both upper and lower veneers in this job -- 28 teeth total, we're told -- that can certainly add up to a fat bill.

That said, it's unclear how much he ultimately paid.

The silver lining here -- it looks like SC is back up on his feet again after breaking his back a few months ago and undergoing a grueling surgery process to get it all fixed up. Word is the dude is still healing and in intense rehab mode right now to restrengthen those muscles.

Another "American Idol" alum is going to fill Simon Cowell's shoes while he recovers from his broken back -- Kelly Clarkson's stepping into the spotlight for "America's Got Talent."

Kelly herself made the announcement Monday with a mock 'AGT' memo sent to "All Staff." It reads, "My friend, Simon Cowell, is doing better now but was in an accident and won’t be able to make Tuesday and Wednesday’s live shows for AGT, but no worries America, someone far wiser, cooler, and hotter is taking his seat!"

It continues, "The unbelievably amazing Kelly Clarkson 😜 You’re welcome in advance!" Kelly will tape Tuesday and Wednesday's live shows alongside Sofia Vergara, Howie Mandel and Heidi Klum. Sounds like it'll just be 2 days until Simon's able to return to his judge's chair.

As we reported ... the record label exec broke his back this past weekend while riding an e-bike out in Malibu. He underwent a 6-hour surgery and is now recuperating. It's unclear if he'll miss any more live shows -- but if he does, his seat will be in good hands if they have KC fill in again.

Comedian Grandma Lee -- who cracked the top ten on Season 4 of "America's Got Talent" -- has died ... according to her family.

Lee's son, Kelly, tells TMZ ... she died Friday afternoon at her assisted living facility in Jacksonville, FL, but it was not related to the coronavirus.

Kelly says his stand-up comic mom was doing shows up until November, but after a gig in Tampa, she fell in her hotel room and broke her hip. Sadly, he says she never fully recovered.

According to Grandma's family ... she passed with her 2 sons holding her hands after spending the past few days reading texts from friends and Facebook posts. They say there will be a service celebrating her life once COVID-19 conditiions allow for it.

Her family adds ... "Heaven just got a whole lot funnier."

Grandma Lee gained popularity in 2009 when she competed on 'AGT' and made it to the finale before being eliminated.

She said at the time that her material is based on truth, adding ... "I go up there and wing it ... but I had to clean it up for the show."

She was 85.

Sofia Vergara is poised to fill one of the 2 seats that are open on "America's Got Talent" ... TMZ has learned.

Sources with direct knowledge tell TMZ ... Sofia met with 'AGT' honchos Wednesday for 2 hours. She was 20 minutes late for the meeting, but that didn't dissuade the decision-makers.

Our sources say Sofia had a big audience over at NBC, from Entertainment Prez Paul Telegdy on down. There were also members of Fremantle present, which produces 'AGT.'

As you know ... Gabrielle Union and Julianne Hough were not invited back for the next installment of 'AGT.'

Our sources say although 'AGT' was top of mind, the honchos wanted to meet with Sofia on a variety of possible projects, including dramas and a possible Spanish language project -- NBC owns Telemundo.

"Modern Family" is in its last season, and we're told NBC wants to get into business with Sofia ... our sources say she's a "global star" who is an extremely versatile entertainer.

As we reported, Union has gone public, claiming 'AGT' has a toxic culture and she was fired after complaining. 'AGT' folks say they routinely rotate judges so nothing was out of the ordinary.

The next 'AGT' airs next month.

Orlando Jones says he and Gabrielle Union now find themselves in the same boat ... speaking out against workplace injustice, and unfair firings, at the hands of the same production company.

The former "American Gods" star came on "TMZ Live" Tuesday to fill us in on his convo with Gabrielle ... after they initially connected through social media posts about his firing from the Starz drama.

'Gods' and 'AGT' are both produced by Fremantle Media, and Orlando says he and Gabby are in very similar situations -- they spoke up at work, and suddenly they were both shown the door. In his case, he says the trouble started with a dispute over his writing credit on 'Gods' ... as a member of the Writers Guild.

As we reported ... Gabrielle said she had no qualms risking her job in the name of fighting against misogyny and racism. She's urged others in her situation to NOT "be the happy negro that does the bidding of the status quo."

Gabrielle Union's speaking out publicly after her controversial firing from "America's Got Talent" ... urging others to risk it all, as she has, to fight misogyny and racism.

The actress spoke on a panel Monday morning, and urged the crowd to NOT "be the happy negro that does the bidding of the status quo." She never called out NBC or 'AGT' by name, but fans there for the panel -- Power of Inclusivity and the Women Leading the Charge -- knew exactly what she was referencing

Gabrielle added, "It's terrifying. There's a solid chance you'll lose your job ... I speak from experience." As we've reported ... Gabrielle feels she was fired because she complained to NBC and 'AGT' producers about racially insensitive situations on set -- including producers giving her excessive notes about her hair, wardrobe and physical appearance.

According to Variety, Gabrielle told the panel it's incumbent on her to speak up and do the right thing ... never mind the company writing those checks. She said, "How many checks do I need? This financial freedom, they're shackles, masquerading as zeros in my bank account."

Waka Flocka Flame believes there were clear racial motives behind Gabrielle Union's 'AGT' firing, and says it's now on the black community to stop supporting companies that have problems with the culture.

Gabrielle's feud with 'AGT' is striking a chord with Waka, and he unloaded when we got him in Atlanta -- telling us he's proud of Gabrielle for speaking out about what was allegedly going down at 'AGT.'

As you know ... Gabrielle feels she was given the boot because she complained to NBC and 'AGT' producers about racially insensitive situations on set -- including producers giving her excessive notes about her hair, wardrobe and physical appearance.

Waka says Gabby's a role model -- because black people in similar situations need to push back and stand up for themselves when someone asks them to change who they are.

Gabrielle also had issues with Jay Leno joking about Koreans eating dogs while he was guest judging. Jay won't say if the joke is racist, and has been mostly mum on the whole controversy.

We ask Waka if we're living in a society that treats racism as a joke, and he says anyone over 40 who is still acting racist is "f***ed up," and needs to stop teaching racism to younger generations.
