Lisa-Marie Presley is desperate to give up her smoking habit - but fears it's the only addiction she can't shake.

The singer has been smoking since she was 15 and admits it has become "a disgusting habit" that forces her to sit outside her home in the freezing cold, because she insists she'll never puff in front of her kids.

She says, "Just because I've got a disgusting habit doesn't mean I have to inundate my children with it.

"I haven't taken drugs since I was 18, but this is the one thing that got me and bit me in the a** that I can't shake.

"I'm ready to quit, but I don't know how."
