Jonas Brothers Talk Bachelor Party Hijinks, Perform ‘Happiness Begins’ on ‘Fallon’: Watch


Nick Jonas, Joe Jonas and Kevin Jonas of Jonas Brothers perform onstage during the 2019 Billboard Music Awards at MGM Grand Garden Arena on May 1, 2019 in Las Vegas,.

Kevin Jonas’ 5-year-old daughter Alena is so proud of her dad she told everyone at school who he is: a Jonas Brother. She also told all her classmates that the Jonas Brothers were coming back before anyone else knew. 

The JoBros dropped by The Tonight Show Starring Jimmy Fallon on Wednesday night to shoot the breeze about their sizzling comeback, changing phone numbers and bachelor party shenanigans.

But it was Kevin’s daughter who stole the show…and spilled the beans. The Bros showed a video of a young Amina bragging about who her dad was, and her dad admitted she spread the reunion story far and wide. 

In another “cool” moment, Nick revealed that he’d changed his phone number and some random guy is now being inundated with messages and words of congrats. The pop stars also played a game of “know your bro,” where each bandmate took turns putting on noise-cancellng headphones while Fallon asked probing questions. Like, what was the wildest thing that happened at Joe’s bachelor party, ahead of his wedding to Game of Thrones star Sophie Turner? 

Cops, for real. “We had the cops on the first night, called on us three times.” Nick explained.

And the worst thing they did as a kid but their folks didn’t find out? Try a visit to the tattoo parlor.

It’s a fun game the whole family can play.

The “Cool” singers also stuck around to perform “Happiness Begins” for the night owls.

Earlier this week, the Tonight Show shared footage of Fallon and the Jonas lads performing “Sucker” on classroom instruments.
