Oh, to be a fly on the wall.
Taylor Swift partied at a Billboard Music Awards after-party Sunday at the Nobu Villa at Nobu Hotel Caesars Palace Sunday following the show.
On Monday, Swift's brother shared a split photobooth shot from the bash, giving fans a glimpse into what looked like an epic time. In the pic, Louis Tomlinson stood next to fellow One Directioner Niall Horan, who wore a crown and kissed Ed Sheeran, who was beside Taylor Swift, who cozied up to beau Calvin Harris, who had his arm around Austin Swift.
