Russel Brand filed for divorce from Katy Perry in London last Friday citing 'irreconcilable differences' as the reason for the split.

Katy Perry rang in the new year partying with a Russell Brand lookalike in Hollywood, a day after he filed for divorce, it has been claimed. Meanwhile Russell was said to be holed up in his hotel room in London as the clock struck 12.

Katy was spotted at the Soho House in West Hollywood on New Year's Eve.

The 27-year-old was laughing with friends in a private room. One source said, 'One wouldn't have ever even known that her husband had just filed for divorce.
At one point, she was talking to a guy with long hair down to his shoulders in the hallway. They were talking for a while. She was smiling and leaning up against wall.

'After midnight Katy and a male friend got on the dance floor, twirling each other around and dancing holding hands. She looked like she was having a great time.'

It had been claimed Katy's constant partying drove him to end their marriage after just 14 months..
