British Singer Lily Allen has dropped two dress sizes - thanks to a London hypnotist. The Smile singer, 22, has shed weight since attending $600-(GBP300) an hour "brain reprogramming" sessions with hypnotism expert Susan Hepburn. She says, "After the hypnotism I want to go to the gym every day otherwise I feel really bad. I just want to get more toned and healthy. I'm really good at the moment - I've never been happier." Of her success with Allen, Hepburn says, "Lily was great, a really nice girl. I'm glad I could help."
