The Jonas Brothers and J-Sisters Were the Cutest Couples at the 2019 Billboard Music Awards

The brothers shared the carpet with their significant others at their first awards show since reuniting.

The Jonas Brothers hit the red carpet on Wednesday for their first awards show since reuniting, and they brought their plus-ones!

The musical brothers, who recently announced the Happiness Begins tour, their first in nearly a decade, are taking the stage at the 2019 Billboard Music Awards to perform their new single, "Sucker." But first, they hit the red carpet dressed in stylish Missoni suits to take some pics with each other -- and with their supportive and stunning wives and girlfriends.

Nick and wife Priyanka Chopra looked stylish and so in love as they posed together on the carpet, with Nick in a blue-and-brown plaid suit set with a black-and-brown striped shirt, and Priyanka in a long, white, embroidered evening dress from Zuhair Murad’s Spring/Summer 2019 Couture Collection.

Kevin and wife Danielle also made a stunning pair, with Kevin in a brown-and-white-striped suit set and Danielle rocking a black, sequined gown with a super-high thigh slit.

Joe's fiancee, Sophie Turner, was also on the carpet -- donning a futuristic jumpsuit from Louis Vuitton's Spring/Summer 2019 Collection -- though she posed for pics with her X-Men: Dark Phoenix co-star Tye Sheridan before the pair presented together during the awards show.

But the whole fam was reunited inside the show, where they sat together and sang along during Taylor Swift's opening performance of her brand-new single, "ME!"

And Priyanka, Sophie and Danielle were front row center for the JoBros epic performance, singing along as they performed "Sucker," along with Nick's solo hit "Jealous," and Joe's DNCE collab "Cake By the Ocean." Nick and Priyanka even stole a quick kiss as the brothers made their way to the stage!
