For a guy whose gal was celebrating her 32nd birthday last night in London, Josh Duhamel sure looks cranky.
Maybe it was just the large rivers of liquid everyone seemed to be imbibing that got him down. Maybe it was the fact that Sienna Miller was tossing what looked like real $100 bills around the room, just not his way. Maybe it was that Diddy had his sunglasses on all night and wouldn't look him in the eye.
Whatever it was, Josh just put on his sour puss and kept it there.
