Pregnant pop star Lily Allen has overcome her nicotine addiction - with a little help from a hypnotist. The Smile singer, who is expecting a baby with her boyfriend Ed Simons of the Chemical Brothers, managed to kick her 20-a-day cigarette habit after a number of sessions with hypnotherapist Susan Hepburn. And the 22-year-old couldn't be happier. Allen's spokesman says, "She is delighted."
