Rhys Ifans ruined his new girlfriend's birthday party on Wednesday night (19.08.08).

The hellraising actor was celebrating Kimberly Stewart turning 29 at London's Bungalow 8 club when he spotted a fellow reveller getting close to his lover.

Rhys grabbed the man, thought to be one of his friends, in a headlock and hurled abuse at him.

He screamed: "F**k off. Don't touch my bird! Let's take this outside, you think you're a big man?"

After security broke up the fight, the 'Notting Hill' star - who is also the frontman of Welsh rock outfit The Peth - careered into a table and sent glasses smashing on the floor.

The troubled 40-year-old 'Notting Hill' star - who split from actress Sienna Miller earlier this year - was seen with a small moustache drawn on his upper lip and said he was a "big fan of Hitler".

He also simulated sex on a friend who had fallen over on the dance floor.

Rhys was eventually calmed down by Kimberly - the daughter of rocker Rod Stewart - who grabbed him by the face to get his attention.

She told 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."

Kimberly eventually made Rhys leave the club and they were seen getting into a taxi.
