Calvin Harris released his highly anticipated single, "This Is What You Came For," featuring Rihanna on Friday, and his girlfriend Taylor Swift gave her stamp of approval.

"OMG," she excitedly Instagrammed along with the song's cover art.

The release of the single comes just a few weeks after Rihanna, 28, and Harris, 32, hit the stage at the Coachella Music Festival in Indio, California, to perform their 2011 song, "We Found Love."

Swift was in the audience -- along with her pals Lorde, Serayah, Fifth Harmony’s Camila Cabello, and model Martha Hunt -- and gushed over her boyfriend's performance with RiRi. "I’ll NEVER forget this moment,” the 26-year-old singer captioned a video from the night, calling it “so incredible.”

That's not all she had to say about Harris. The "New Romantics" singer praised their relationship in Vogue's May issue, saying the couple is "just taking things as they come" at the moment.
