It seemed to be a drama-free night at the 55th Annual Grammy Awards on Sunday! Instead of awkward run-ins with exes and celebs attempting to avoid each other, things look like they were happy-go-lucky in the audience and backstage at the show -- and some of the best celeb interactions were even caught on camera.

Check out all the star-power moments, from Ellen DeGeneres sneaking a peak at Katy Perry's cleavage, to Lena Dunham congratulating her man after several Grammy wins, after the jump!

Another Grammys, here and gone. So who goes down in history as having some of the best music of the past year?

As infectious and ever-present as it was, Carly Rae Jepsen's "Call Me Maybe" didn't take home either of the two awards it was nominated for, losing to Adele (of course) and fun.'s "We Are Young." However, if you turned on the radio even once in 2012, you likely heard one of two big winners — fun., who also won the coveted Best New Artist award, and Gotye,  who came home with Record of the Year, Alternative Album, and Pop Duo/Group Performance.

Catch the complete list of winners after the jump!
