Pete Doherty has been accused of cheating on fiancee Kate Moss after picking up a girl in a nightclub.

Following a promotional event for his collection of diaries The Books of Albion, Pete was spotted at Crystal nightclub in London’s West End on Thursday night.

A source close to the Babyshambles star told the Sunday Mirror: “When he first arrived Pete was showing off, standing on his chair and dancing like a loon. Then he wandered about and ended up talking to this girl in a revealing tight white dress.”

“She was wearing a choker around her neck and was very well groomed. She had the same pointy features of Kate Moss and well-defined cheek bones. You couldn’t help but see a similarity.”

“They went up on the street for a while then came back inside, where they had an intense chat for ages. There was lots of flirting and laughing.”

Pete, the mystery woman and two friends were then seen leaving together in a taxi in the earlier hours of Friday morning, to continue the party at a friend’s house. The source reports that Pete and the woman disappeared into a bedroom together and they didn’t reappear for several hours.

The source added Pete may have been inspired to infidelity after a fall-out at home: “Pete and Kate had a serious argument during the week and he just decided to go on a bender. Kate was calling around to see if anyone knew where he was but everyone rallied around him to keep her in the dark.”

“She is very jealous about other women. She used to hate other girls staying at his flat before he moved in with her. Hearing about him spending the night with another girl will eat her up. They have a tempestuous relationship at the best of times.”
