What is the name of this song?

I just saw part of the music video, but i never heard the name or who it was by! It was just right before Gossip Girl, just now! It's a music video w/ a lot of girls in a club and this guy and it sounds like he was saying something about a Silver Moon? The girls are in skimpy clothes and stuff and he's just a normal guy, and I think some lyrics were "Maybe I was wrong, maybe blah blah?" I really want to know because i liked it! It sounded like rock or pop or something thanks!
