Who the F Is Simon Rex?

He was an MTV VJ, has been in two of the "Scary Movie" films and briefly dated Paris Hilton -- who hasn't? -- but Simon Rex still couldn't get recognized last night in Hollywood.

After chatting up a TMZ photog, a fellow clubgoer tried to steal a little of Simon's camera time by hurling insults at the "Shriek If You Know What I Did Last Friday the Thirteenth" star.

Don't hate.
