Looking like an imitation Brad Pitt from "Fight Club," sexy Maroon 5 singer Adam Levine celebrated Halloween last night. This love has taken hold -- of everyone!

Even with the fake blood splattered on his head, the singer still can't pull off the scary look! First rule of fight club -- keep ya shirt off!
