Cheryl ColeGirls Aloud’s Cheryl Cole and Nadine Coyle have both reportedly turned to hypnosis to help them give up smoking.

A source told the People newspaper that Cheryl is being spurred on to drop the habit by footballer husband Ashley Cole: “Ashley’s been trying to get Cheryl to quit for ages. He’s superfit and hates the smell.”

“Nadine’s been smoking more since her break-up [from Jesse Metcalfe]. And they know it’s going to be harder to smoke now the government ban’s in place.”

“Both girls want to give up but it’s a hard habit to break. Trying hypnosis has been suggested to make it a whole lot easier.”

“They also think doing it together will be a good way to encourage each other.”
