Back in July, it was revealed that Taylor helped to co-write Calvin’s collaboration with Rihanna.

Before singing the song, Taylor spoke to the crowd, saying “As a songwriter, I…, The most rewarding feeling in the world is writing something and having the crowd sing it back to you because they know the words. It’s the coolest feeling in the world. I’ve never performed this song live before. But if you know it, maybe you can sing along and I can get to know what that feels like — to have it sung back to me.”

Calvin first released the song while he was still dating Taylor, but at the time neither mentioned her involvement in the track. She did however show her support by wearing a jacket bearing the song’s artwork.

BLEACHELLA ??
