Taylor Swift and Panic! At the Disco's Brendon Urie gave their first live performance of their latest single "Me!" at the 2019 Billboard Music Awards on Wednesday night (May 1).

The performance began with a marching band striding toward the stage, dressed in pale pink pastel hues. Swift came out in a fringy, glittery dress resembling a baton twirler's costume. Meanwhile, Urie dropped from the ceiling Mary Poppins-style, floating while holding an umbrella, which he also did in the "Me!" music video. The crowd went wild. Swift joined him and the duo began to dance together, much to everyone's delight.

The cameras panned to the Jonas Brothers, who were dancing along to the performance along with crowd shots of fans and celebrities alike grooving and taking videos on their phones. The pair introduced themselves mid-song and welcomed the audience to the Billboard Music Awards — their duet opened the show.

They of course got a standing ovation, with host Kelly Clarkson offering up high compliments and asking the crowd how much they loved her.

Swift is nominated for Top Female Artist and Top Touring Artist on the BBMAs despite not releasing any new music within the judging period. Urie is nominated for Top Duo/Group, Top Rock Artist, Top Rock Album for Pray for the Wicked, and Top Rock Song for "High Hopes!"

The 2019 BBMAs are being held in Las Vegas.
