Over the weekend, 'Glee' stars Lea Michele and Cory Monteith attended the Coachella music festival, where the on-screen and off-screen sweethearts got very affectionate with each other.

A source told US Weekly the actors arrived separately to the Lacoste L!VE desert pool party on Saturday. Michele spent "at least half an hour" talking with Lauren Conrad before later meeting up with Monteith. When Cory arrived, Lea let the world know on Twitter:

The source said that when Monteith tracked Michele down, "he tapped her on the shoulder and she was so excited to see him. She threw her arms around him and they hugged and kissed on the lips." The couple went to a private cabana and continued to get friendly. "Their arms were constantly around each other and they were talking very close," the source added. "They definitely looked like a couple with how affectionate they were being in public." The 'Glee' stars apparently spent the rest of the evening taking in their favorite bands. Michele tweeted that she saw the Shins, Bon Iver and Radiohead. Monteith ended the night with a simple tweet, no doubt partly inspired by his time with Michele:
