British pop star Lily Allen fears Amy Winehouse has descended into drug addiction to escape the pressures of fame. The Smile hitmaker, 22 - who has vowed to stay in her control of her life - moaned on her MySpace page earlier this year (May07) of being "s**tter" than Winehouse. But Allen's animosity has turned to pity for the pop star, who last month (Nov07) abandoned her tour on doctors' orders following a series of disastrous concerts. She says, "I just feel sorry for her, to be honest. If you had a drug problem, would you want cameras shoved in your face the whole time? "She probably feels really uncomfortable with all the attention and her way of dealing with it is locking herself up in her flat taking drugs, escaping to a world where things aren't so surreal and weird."
