Taylor Swift wrote a bunch of songs about her heart-wrenching breakup with Harry Styles, but the singer's One Direction bandmates, Louis Tomlinson and Niall Horan, were caught hanging out with the pop star during her 2015 Billboard Music Awards after-party.
The "Shake It Off" singer's younger brother Austin Swift posted a photo of them all goofing off with Ed Sheeran and Taylor's current boyfriend, Calvin Harris. (You're about to get major Talvin feels!)
It seems like an absolutely star-studded bash. Everyone from the girls of Fifth Harmony to Hailee Steinfeld were there. While it's a bit odd to see Taylor hanging out with her ex's BFFs, they broke up a few years ago — everything's probably all cool between them! Plus, Louis and Niall are super-close to Ed, so that's probably how they scored the invite.
