Calvin Harris closed out the first weekend of Coachella with some major guest appearances from Big Sean and Rihanna.

Big Sean performed his song "I Don't Fuck with You," while Rihanna came out dancing and occasionally singing along to "We Found Love," with her vocals from the track being heard half the time she was on stage.

Nonetheless, it was a big get. And Harris' girlfriend Taylor Swift seemed to approve, sharing a video of herself and her friends watching Rihanna on Instagram with the caption, "I'll NEVER forget this moment."

Watch footage of both Rihanna and Big Sean's appearances below.
