Going to the Billboard Music Awards and partying with your famous sister’s A-list friends isn’t a bad way to celebrate your college graduation.

That’s how Austin Swift, younger brother of Taylor, spent Sunday evening after graduating from the University of Notre Dame in the morning. It was a day of sibling support: Taylor attended the commencement ceremony in Indiana before whisking her little brother to Las Vegas to watch her sweep the awards show and celebrate afterwards with her squad.

Swift could be seen cheering for the “Bad Blood” singer from the front row throughout the show and Tweeted a pic on Monday of the afterparty.

“Last night was a wild ride #DoneWithCollege,” he captioned a photobooth strip of three prop-heavy photos of Swift, Taylor, her rumored boyfriend Calvin Harris, Taylor’s bestie Ed Sheeran and One Direction‘s Louis Tomlinson and Niall Horan.

Taylor and Harris look extra cozy in the photos – no word on whether One Direction member and former Taylor love interest Harry Styles was also in attendance.
