Lily Allen has reportedly turned to hypnotherapy in a bid to quit smoking now that she is pregnant.

Lily is said to have sought the services of top Harley Street guru Susan Hepburn, who helped the singer lose weight by training her mind not to crave fatty foods.

A pal of Lily’s tells The Sun: “She wants to crack this. She realises it will be a struggle but her baby is more important.

“Lily is aware that she is a role model and wants to portray a positive image of herself for young people to look up to.”

The singer is desperate to stub out her 20-a-day habit after learning she is expecting her first child with boyfriend, Ed Simons of the Chemical Brothers.
