Actor Chris Evans and, uh, "socialite" Larry Birkhead were both spotted - albeit separately - at One on Sunset last night.

Chris left empty-handed, but a female fan handed Larry a red rose upon exiting! (Maybe it's time the lady found a different celeb to admire, right?)

Don't forget to check out the end of the video to see a clubgoer passed out on the strip - looks like he partied too hardy!
