Pop star Lily Allen has been arrested for allegedly attacking a photographer outside a nightclub in central London. The 22-year-old singer attended the police station at a pre-arranged time to be questioned in connection with an allegation of assault. She was released on police bail over the alleged assault on photographer Kevin Rush near the Wardour club in the Soho area on March 13. A Scotland Yard spokeswoman confirmed Allen was "arrested in connection with an allegation of assault. She has been bailed to return on a date in late July." The incident took place in March after Allen left a party she was hosting at The Wardour club in London. As she walked to the nearby Groucho club - a favorite haunt of her father Keith Allen - she suddenly turned on Mr. Rush, who was standing among a group of photographers. She is alleged to have lunged forward and hit him in the face, leaving him reeling. Allen was accused of a previous attack on a photographer at the Brits awards. It was alleged she took off her stiletto and attacked a photographer as she left empty-handed, losing out to rival Amy Winehouse ... In another rant, Lily complained that she is a hate figure in the UK, but is treated like royalty in the US. She said: "In LA some of the paparazzi are really nice. But I think people hate me in England. "I'll write 10 million nice things, then I'll write one thing that annoys me and it's like: 'Lily Allen slams Madonna'. And I become that person that badmouths people, which I'm not." Yeah, it sounds like Miss Lily has a few anger management issues to work out. Regardless of the fact that she believes the press "hates" her she really should rethink her strategy of hitting back at her perceived detractors by actually hitting back at her perceived detractors ... um, especially when they photograph or video tape her physical attacks. She'd prolly be much more successful working out her anger issues if she just assaulted her underlings in the privacy of her own home ... just like Naomi Campbell. Oh wait, she actually got busted for doing that. Hey, here's an idea ... how about not hitting anyone at all ... that might work.
