Backpack Kid's signature dance, the Floss, is already immortalized in Fortnite ... and, while he says he never got a penny from the game, he's not sweatin' it -- 'cause he's banking on a new dance.

BK, aka Russell Horning, was at Tuesday's first ever E3 Celebrity Pro-Am, where celebs like Pete Wentz and EDM DJ Marshmello squared off for $1 million jackpot for charity.

The video game is worth about a billion dollars and featured Russell's moves, but his moves were retired when the new season of the video game launched.

Fortnite never cut Russell, who's 16, a check for the feature, but Russell says he could care less because it was a huge honor, and he's already moved on to a new dance he's aptly calling "The Money Dance." He gave us a preview.

Former "Dance Moms" star Nia Sioux's crossover into scripted TV on "The Bold and the Beautiful" is keeping her pockets deep now that she's no longer on the dance competition reality show.

We got ahold of her minor's contract for the soap opera and Nia, who's 16, is making $2,500 per episode. She's already appeared in 6 episodes this year.

Unclear how long her story arc will run but, if she does return next season, her rate goes up to $2,800.

Anthony Bourdain's 11-year-old daughter got onstage and sang -- 2 days after his suicide -- in a performance her mother called "strong and brave."

Ariane Bourdain was singing with her band Sunday at an NYC venue called DROM. Anthony's ex, Ottavia, posted a pic of Ariane with a caption personalized for Bourdain: "Our little girl had her concert today. She was amazing."

Ottavia added that Ariane was wearing a pair of black, studded boots her father had given her.

Anthony frequently talked about how much he loved Ariane and, in general, loved being a father.

Ottavia cryptically ended her note with, "I hope you are having a good trip, wherever you are."

Britney Spears has no shame in her wedgie game -- giving herself one on purpose -- so her hot buns could get some sun.

Brit's been keeping busy while vacationing in Miami with her kids. She hit the pool, did some snorkeling and even hit the water for a jet ski session on Wednesday ... where she fell victim to a now-infamous atomic wedgie.

The all-time greatest come-up is complete -- Jeremy Meeks has a baby boy with his girlfriend, Chloe Green, and the kid's name might say a lot about their relationship.

The billionaire heiress and her man -- formerly known as the "Hot Felon" -- announced the birth of Jayden Meeks-Green, who was born May 29. They both posted a close-up shot of Jayden gripping Mom and Dad's fingers.

Yes, the kid's last name is hyphenated, and yes ... Chloe's name gets the last word. At least for now. As we reported, we kinda knew it was gonna be a boy based on the baby gear they stocked up on back in February.

Jeremy and Chloe started dating just about a year ago, not too long after he was released from a California prison and launched his modeling career.

As for the last name -- it's possible they'll drop the hyphen if Jeremy and Chloe get married. Then again, Mom is heir to the Topshop fortune, so ...

Mazel!

Janet Jackson's call to police over the weekend and the stories that followed are connected to her custody trial with Wissam Al Mana, but she's not the one stirring the pot ... according to our sources.

Janet's London custody case is contentious ... not because either parent thinks the other is unfit. Our sources say Janet's having trouble because she wants 1-year-old Eissa in the U.S. with her. Problem is ... Janet chose to move to London to be with Wissam and that's where Eissa was born. It was her decision to move back to the U.S. after they broke up, and that may be giving Wissam the edge.

Janet was indeed upset with Wissam over the weekend and we've learned she called the cops twice -- once on Friday and again Saturday. Thing is ... it was all about Wissam not making Wi-Fi available to Janet's nanny because cell service was spotty in Malibu and Janet wanted communication.

Stories initially surfaced that the nanny became frightened by Wissam's "aggressive behavior." The way the initial story went ... she was "terrified by his behavior and locked herself in a bathroom so she could contact Janet." That story did not come from Janet ... it came directly from her brother, Randy.

Sources connected to the former couple say Randy is fanning the flames of conflict to help Janet gain an edge in her custody case. They say her call had nothing to do with a terrified nanny. It was all about cell phone service, although she did drop a reference to drug use.

We're told cops went out and were literally there only a few minutes before they realized nothing was wrong and told them to deal with the cell phone service issue themselves.

There's no denying Khloe Kardashian and Tristan Thompson make super cute babies, because 2-month-old True could make anyone's heart melt ... although, she needs a tissue.

Khloe shared a video Tuesday morning of True propped up on a couch dolled up in a pink tutu and giant bow. The tiny model definitely looks more like her dad. She got his nose, but she's got her mom's knack for entertaining when the camera's on her.

You'll see what we mean when she lets out a ferocious, mouse-like sneeze.

Tyrese is making plans to move his daughter to Atlanta -- away from her mother -- because he says she'll have a much better life there in his new mansion ... according to docs.

Tyrese filed docs requesting primary custody of 10-year-old Shayla. He and his ex-wife, Norma Gibson, have had shared custody up to this point, but he says Norma is marginalizing his custodial time with their daughter.

According to the docs, obtained by TMZ, Tyrese will provide a "stable and loving" environment for Shayla in his 23,000 sq. ft home in Atlanta ... which he points out is in an "affluent and safe neighborhood." He adds, Shayla already has her own room decorated in her favorite colors, and she made plenty of friends while she was there last year.

He also says she'll attend a top-notch private school there. In the docs, he says another selling point is fewer paparazzi, and the 9th installment of the 'Fast and Furious' movies will be shot in the ATL.

Overall, Tyrese says he's fed up with being cut out of Shayla's life.

He says there have been at least 2 incidents in the last year when Shayla was ill, once with flu -- and in the docs he rips Norma for only contacting him to get insurance info. He claims she refused to fill him in on any other info, such as a diagnosis.

Yep ... that's YouTube star Rebecca Black, best known for her 2011 earworm, "Friday" ... and we have a feeling these photos will be just as catchy for her fans.

Rebecca hit the pool at the Dream Hollywood hotel over the weekend. Apparently, she doesn't ONLY get down on Fridays. She's looking a helluva lot more grown up than the teenager most remember singing that annoying (we say that lovingly) one-off hit.

The Royal Family will NOT retreat from public view in the wake of an ISIS call to action against 4-year-old Prince George ... sources directly familiar with the situation tell TMZ.

As we reported 32-year-old Husnain Rashid encouraged ISIS to attack the boy who is third in line for the throne -- attack him at his school.

Our Royal sources tell us, Prince George is scheduled to appear June 9 with his family on the Buckingham Palace balcony for a ceremony in full public view, and the event will absolutely take place.

As for attending school, the Palace is well aware the location of the school is public record and the boy will continue attending.

The family has almost remarkably been seen in public ... check out this pic taken just last Sunday at a public park where Kate Middleton, Prince George and Princess Charlotte attended the Houghton horse trials.

Danielle Bregoli might not have known who LeAnn Rimes was, but LeAnn definitely knows who she is ... and on top of that, she's down to collaborate with Bhad Bhabie!!

We got LeAnn heading into the Abbey in WeHo on Thursday night and told her we schooled Danielle on LeAnn's legacy. After all, Danielle had just become the youngest female artist since '97 to score 3 Billboard Hot 100 hits. Last person to do it? LeAnn.

But when we told Danielle about this she wondered who LeAnn Rimes was ... asking if she's Busta Rhymes' sister. Hilarious.

Check it out ... LeAnn's down to hook up with Danielle in the studio. And all we can say ... wonder what they'll come up with to blend their unique styles.

BTW ... LeAnn was SLAYING on her way to the Abbey. Pure fire.

Prince George was the target of a terrorist, and the man who encouraged ISIS to carry out a plot at the boy's school has just confessed.

32-year-old Husnain Rashid had maintained his innocence since his arrest last November, but in a court hearing he now admits he carried out a number of terroristic acts and engaged in preparation for other attacks.

Rashid posted a pic of Prince George -- 3rd in line to the throne -- next to a silhouette of a jihadi fighter. He posted the address of George's school and wrote, "even the royal family will not be left alone."

He'll be sentenced June 28.
