Taylor Swift may have been the belle of the ball at the Billboard Music Awards on Sunday — where she racked up a whopping eight trophies — but it was her little bro Austin who was really having the most momentous weekend.

The 23-year-old entered the real world in epic “Style” on Sunday, first graduating from the University of Notre Dame, and then tagging along with Tay to the BBMAs later that night. Ever the proud older sis, Taylor even flew out to South Bend, Indiana, to attend the commencement ceremony and cheer him on from the crowd.

Taylor also gave Austin a heartfelt shout-out during her acceptance speech for this award, saying, “Early this morning I watched my brother Austin graduate from Notre Dame...to anyone who’s graduating this year, this is for you.”

Since the Swift sibs clearly had a helluva lot to celebrate after the show wrapped, they hit the after-party in stunning fashion alongside a slew of famous friends including Fifth Harmony, Adrian Grenier, Jennifer Lopez, and David Guetta.

In what might be the most FOMO-inducing photo booth pic we’ve seen since Tay’s 25th birthday party last year, Austin shared a playful snap of him and his sis getting silly with claws and animal masks alongside Calvin Harris, Ed Sheeran, and One Direction’s Niall Horan and Louis Tomlinson.

Noticeably missing was Tay’s ex Harry Styles, who skipped town instead of hitting the after-party circuit, a 1D rep told E! News. Womp, womp.

So, how does Austin Swift’s graduation weekend trump every other college graduates’ festivities? Let’s recap: After earning his diploma, he flew to Las Vegas to attend a fancy-shmancy award show. Then his victorious sister bragged about him on national television. And THEN he partied alongside more famous people than Taylor had in her “Bad Blood” video. You know, just the casual, run-of-the-mill celebratory stuff. Definitely not a bad way to kick off post-grad life!
