Tying The Knot

Migos' Offset got down on bended knee in front of some 19,000 people and proposed to girlfriend Cardi B Friday night at the Philly Powerhouse concert where they were both performers ... oh, and she said YES!

Just last week it seemed like the couple was on the brink of breaking up when Cardi posted she was "single" before backtracking and saying she "exaggerated a lil bit" on her social media.

The two have been together since the beginning of the year when they were spotted leaving a Super Bowl event together for the first time in February.

Watching the video you can tell Cardi B had no idea what was coming her way. #Mazel.

Katy Perry got her 15 minutes of fame this weekend ... in the wedding crashing world, that is.

Katy stumbled upon a wedding reception Saturday at a Four Seasons Hotel she was staying at in St. Louis -- where she was performing the next day. We're told she asked the bride and groom, Blonie Dudney and Hayley Rosenblum, if they were cool with her crashing for a while.

Perhaps to no one's surprise ... they were.

Eyewitnesses tell us Katy and about 30-40 members of her touring crew joined the wedding guests for some dancing and mingling. Katy mostly hung out with the newlyweds, and was even ramping up to perform for everyone ... but pulled the plug when things got a bit rowdy. Although she did stay to take some epic photos.

Sources say Katy stayed for roughly 15 minutes and danced a majority of the time. Some of her entourage hung out a bit longer after she left.

That's one for the books ... and the wedding album.

Gucci Mane and Keyshia Ka'oir finally tied the knot in front of TV cameras, all in white, with a super famous guest list, and best of all ... BET picked up the tab!

Gucci and Keyshia got hitched Tuesday night at Miami's Four Seasons Hotel, draped from head to toe in white outfits ... a theme they kept going from Gucci's knee-less proposal.

As we reported ... BET had cameras rolling for the nuptials, which aired live. The couple scored $650k for the deal -- which includes a 10-episode series -- plus the all expenses paid million-dollar wedding. Great work if ya can get it!

Keyshia and Guwop's hip-hop pals 2 Chainz and Diddy were there, along with 'RHOA' stars Kim Zolciak-Biermann and her daughter, Brielle -- plus Karrueche Tran, Big Sean, Rick Ross, Monica and more. You'll recall ... their invitations were legit.

Congrats!

Jewel's rodeo champ ex-hubby, Ty Murray, is gettin' back on the horse ... when it comes to love and marriage.

Ty and FOX Sports reporter Paige Duke tied the knot September 30 at the Quarry at Carrigan Farms in North Carolina. They had the place decked out to be every cowboy/girl's dream.

Sources close to the couple tell TMZ ... Ty and Paige handed out homemade apple butter and personalized tobacco bottles as party favors to their 200 or so guests. Best of all, Ty and Jewel's son, Kase, was dad's best man.

And how's this for a real cowboy? Ty's wedding band was made out of elk antler and metal from his father's wedding ring. Paige went more traditional ... with a Cathy Waterman designed diamond ring.

Joe Jonas is an engaged man -- 'cause he just announced he proposed to girlfriend Sophie Turner ... and she said yes!

Joe posted the news on social media Sunday with a photo of Sophie's hand over his with a sweet rock on her ring finger. He captioned it ... "She said yes."

Joe and Sophie have been dating for about a year on the dot, and have seemed inseparable ever since ... going on super cute dates and basically becoming the definition of "relationship goals."

When you know, you know ... we guess.

L.A. Lakers rising star Larry Nance Jr. is officially off the market ... 'cause the NBA baller just proposed to his college sweetheart with a MASSIVE diamond ring!!

The 24-year-old and his longtime girlfriend, Hailey Pince -- a fellow U. of Wyoming alum -- announced the big news on social media Tuesday by showing off the huge rock.

LNJ and the aspiring model have been dating for over 3 years ... and he explained his decision to pop the question by channeling his inner Beyonce, saying "I liked it, so I put a ring on it."

Nance can reportedly make up to $7 million over the next 3 years ... so yeah, dude can afford to splurge on his girl.

Gucci Mane's wedding invite glistens like one of his old grills, and it also put a $50,000 dent in his wedding budget!

Guwop opted for his real name, Radric Davis, on the super fancy invitation he and Keyshia Ka’oir sent out for their million dollar wedding this fall. It's being filmed for BET, and will clearly be an over-the-top event.

Each invite is a mirror-inspired booklet adorned with Swarovski crystals inside ... each for a mere $1k.

We're told 100 people are on the guest list with plus-ones, but only half got the fancy document. Most of them were Gucci's celeb pals and collabs like Drake, Rihanna, The Weeknd, Selena Gomez, Pharrell, Diddy, Rick Ross, Monica, Trina, Migos and Solange.

If you're wondering ... it's their international guests who aren't getting the invitation, due to shipping costs. Of course, seems late for cutting corners -- the wedding's going down at the Miami Four Seasons, after all.

Here's the very first pic of Mr. and Mrs. Ronda Rousey and Travis Browne!!

You can see Ronda with a big 'ol smile on her face while sporting a fancy Galia Lahav wedding gown during the wedding festivities in Hawaii this past weekend.

Ronda had said the reception was going to be a Hawaiian-style backyard BBQ with their closest friends and family ... and judging by their faces, it was everything they hoped for!

Dana White had said he got an invite to the ceremony -- but it was on the same day as the McGregor vs. Mayweather fight ... so, he couldn't make it.

Ronda's sisters served as the bridesmaids and her mother, AnnMaria, was also there!

Congrats!

Ronda Rousey won't be ringside for McGregor vs. Mayweather ... 'CAUSE SHE'LL BE GETTING MARRIED!

Dana White revealed that Ronda will be tying the knot with longtime boyfriend Travis Browne on Saturday. The two got engaged back in April.

White told Rich Eisen he was invited to the wedding but obviously won't be able to attend. Ronda previously announced on "Kelly and Ryan" that the wedding will go down in Hawaii.

As for Ronda's career, Dana says she hasn't retired -- but says she's in a great place and super happy.

What do The Chainsmokers and Adam Sandler have in common? They both can play wedding singer.

The duo's Andrew Taggart belted out several Chainsmokers cuts, including hit song "Closer," over the weekend at his buddy's wedding reception at Philly's Rittenhouse Hotel. But instead of a video wall, Andrew had a band behind him.

We're told Andrew and the groom went to Syracuse together, and he was one of the groomsmen in the wedding, while Alex Pall, the other half of the duo, was a guest.

It's pretty cool considering the duo performed for thousands at the Convention Center in L.A. and there were only about 200 people at the wedding.

Rachel Lindsay musta been one helluva 'Bachelorette' -- 'cause she can be with her fiance and her exes from the show in one room ... sans any awkwardness.

Rachel and her hubby-to-be, Bryan Abasolo, celebrated their engagement in Miami Beach Saturday night at a little place called Bodega Taqueria y Tequila ... with 3 other contestants from her season tagging along for the ride.

William Gaskins, Matt Munson and Josiah Graham all came out to rage with the couple. We're told there are no hard feelings ...pretty obvious from the chumminess.

Rachel, Bryan and the rest of the gang fired up the festivities at midnight and went until 3 AM -- with the help of 3 bottles of vodka and a bill totaling $1,500.

To marriage ... and people we used to date.

Kris Jenner took in a comedy after dinner -- a question about her youngest daughter getting married.

Kris was leaving Nobu Los Angeles Thursday night with bf Corey Gamble when a pap asked if Kylie's boyfriend, Travis Scott, has her blessing to join the family ... and she thought it was hilarious.

Hard to say how the couple should feel about Kris' reaction. On one hand, Kylie's only 20 so her mom may just think it's ridiculous to think about her tying the knot.

On the other hand ... ouch.

Travis should probably stick to giving Kylie butterflies for a while ... and hold off on a ring.

Amber Rose wants 21 Savage to put a ring on it ... and she'd rather talk about THAT than her ex-mother-in-law suing her.

Amber was at LAX Wednesday where we wanted to get serious for a minute -- she's being sued by Wiz Khalifa's mom for defamation. Amber's since lawyered up but it's clear when we got her she was in no mood to talk about it.

But Amber was quick on her feet ... pivoting to Savage, who clearly tickles her pickle.

You're officially on notice, Savage!

Rachel Lindsay must know it's just a matter of time before the world loses interest in her season of "The Bachelorette" ... so she's milking the spotlight.

Rachel and her new fiance, Bryan Abasolo, were swarmed by paps Tuesday as they arrived at the BUILD studio in NYC ... and they took their sweet time to suck face for the cameras.

In her defense, Rachel's season finale was Monday night -- so it makes sense she'd be making the rounds, posing at all the stops along the way.

Still, this display of affection is a bit too on the nose for us not to cringe. Congrats, though ... here's hoping they're couple #6 to actually tie the knot for 'Bachelor' Nation.

Rachel Lindsay likes her fiancee the way she likes her coffee -- Colombian, and there to wake her up in the mornings ... which is why she chose Bryan on "The Bachelorette" finale.

Rachel gave contestant Bryan Abasolo the final rose during Monday night's final episode of the season, cutting both Eric Bigger and Peter Kraus in the process -- the last black and white guys on the show, respectively.

Eric took his elimination like a champ, all things considered. He even got let go before Peter, who's been having serious commitment issues all season ... but bowed out in grace.

As for Peter ... he kept it painfully real. Basically, he didn't want to get engaged to someone he just got to know and fell in love with over 2 months. Bryan clearly did.

Montell Jordan sprang a huge surprise on an unwitting bride over the weekend, and traveled halfway around the world to do it.

Sources close to Ryan Deluca -- who founded bodybuilding.com and runs a VR company, Black Box -- tell TMZ he and his bride-to-be, Nelya, learned a whole 1st dance routine to Montell's hit, "This Is How We Do It." But Ryan wanted to go the extra mile, and get Montell live.

We're told one of Ryan's groomsmen was Creston Thornton, a Live Nation bigwig ... and he called music agent Jamie Adler ... who scored Montell for the Boise ceremony. As they say, it's all about who ya know.

Still, getting Montell to Idaho wasn't easy. We're told he flew private from Rome to Vegas (where he also performed that day), and finally to Boise. Ryan covered travel costs and the $10k appearance fee.

MJ performed 3 songs and, most importantly for Ryan ... Nelya loved the surprise.
