Sienna Miller's ex Rhys Ifans is clearly still out of control and boozing it up with new girlfriend Kimberly Stewart.
Last night the couple went out to Bungalow 8 nightclub to celebrate Kim's bday, but the night was almost ruined when Rhys got into a fight with a guy he thought came too close to Kim.
Rhys reportedly put the guy in a headlock and screamed: "F**k off. Don't touch my bird! Let's take this outside, you think you're a big man?"
Security had to break up the fight and Kim was overheard telling him, "F**king calm down. I've had enough of this s**t, Rhys, don't do this. It's my birthday, stop acting like you're 12."
Clearly this guy has some issues. We just feel bad that he's Kim's problem now. Sloppy seconds are never a good idea sweetheart!
