Lily Allen has been fined $2,000 for an ice cream fight.

The 'Fear' singer received the costly cleaning bill after causing havoc backstage to celebrate the end of the North American leg of her tour.

The star wrote on Twitter: "Had a massive ice cream fight, dressing room based, cost me $2000. End of tour, time to get mashed. Props to natalie portmans shaved head."

Lily Allen was terrified her career was over because of her wild lifestyle. The "Fear" singer became famous for her drinking and partying when she released her debut album "Alright, Still" in 2006, and was worried it would take the attention away from her talent as a singer and songwriter.

She said: "I took a bit of a beating the first time around. I became more famous for being a train wreck than a singer. I didn't think I was capable of writing songs and making music."

Katy Perry says Lily Allen "looks hot." The two singers became embroiled in a war of words after the U.S. star described herself as a "slimmer version of Lily Allen" but the "Hot N Cold" star insists she never meant to cause offense.

Katy told Heat magazine: "I really didn't mean to upset her. What I actually said was that I was a skinnier version of Lily Allen and a fatter version of Amy Winehouse. But Lily is skinny now. She is hot - she looks really good."

Kate Moss beat Lily Allen in a drinking contest. The 35-year-old supermodel challenged her friend to a cocktail making and drinking competition at the customized bar of her London home, and was delighted to come out victorious.

A source said: "Kate and Lily each made up various cocktails and had a competition to see how many they could drink."

Lily Allen feels like a "caged animal." The 23-year-old singer says the paparazzi make her feel trapped and sometimes she dreads going out.

Lily said: "Sometimes it makes you feel like a caged animal, being followed by 20 men with cameras all day. The second I walk out the door, it's like that."
