Supermodel Naomi Campbell insists she has "learned her lesson" after behaving badly in 2007 - and has vowed never to throw a mobile phone again. The British catwalk star has landed in court on a number of occasions, accused of assaulting staff members - and earlier this year (07) she was sentenced to community service after pleading guilty to a charge of reckless assault - in which she threw a mobile phone at her maid Ana Scolavino. But Campbell is adamant she's not ashamed of her misdemeanours. She says, "It's been a very interesting year. I've learned many lessons, like no more phones. "In New York I'm the bad girl, I'm the good girl, I'm a controversial girl, and I've been through so much in this city. I'm a recovering addict and alcoholic, of which I'm not ashamed."
