Tana Mongeau and Jake Paul Wedding: Multiple Wedding Dresses, a Fight and More!

The YouTube stars have tied the knot.

Jake Paul and Tana Mongeau are officially married.

The YouTube stars tied the knot on Sunday, in an appropriately raucous ceremony that saw the pair's cadre of friends fly out to Las Vegas for the occasion.

Leading up to the big night, Mongeau took to her Instagram Story to share a slew of snapshots showing her and Paul getting ready for the event, flying out to Sin City with their friends, and generally having a wild time as they prepared to tie the knot.

While the event itself could be watched by fans -- who were willing to pay -- as it streamed online, Mongeau herself confirmed that they'd officially gotten married when she took to Twitter to explain how a fight had broken out at the ceremony.

"Someone just threw a glass of champagne at Jake and I at the f**king altar holy f**k HAAHAHAHAHAHA. Jana don’t need no press," she tweeted. "Wow. Just married. Honestly made it better.... to slow dance while they scream. I love you @jakepaul."

An eyewitness tells ET that the fight appeared to be staged.

Before their wedding, Mongeau showed off her style in two different wedding dresses, one for her arrival to the grand occasion, and another for the actual exchanging of vows.

For her first look of the night, she opted for a traditional look, rocking a curve-hugging all-white gown with lace detailing and a long, floor-length lace veil.

However, Mongeau switched things up when it came time for her actual wedding ceremony, and changed into a stunning gown that featured a white corset-style top with sweetheart neckline and a voluminous, ruffled pink and white skirt and train.

And in true Jake and Tana fashion, the newlyweds also had their names and wedding date painted on the building of the wedding venue. 

This is the first marriage for both 22-year-old Paul and 21-year-old Mongeau, who was previously in a relationship with Bella Thorne. Paul proposed to Mongeau last month as she celebrated her milestone birthday in Las Vegas when he brought Mongeau on stage at Drai's Nightclub and popped the question. She later showed off her giant ring on her Instagram Story, and then confirmed she and Paul were engaged on Twitter.

"JAKE JUST PROPOSED," she wrote. "I’m....... engaged.................." 

Earlier this month, she shared a few of their engagement photos on Instagram.

"Bet you didn’t think we’d be engaged for this long... #ThePauls ?," she wrote.

Paul actually revealed their wedding date when he made a surprise appearance during Mongeau's panel at VidCon on July 14, and read her a poem.

"Welcome to the Paul family, we welcome you with love. From the moment I met you, we fit like a glove," he said. "The world can question our fate, but on July 28, you can all save the date."
