Ronnie Wood struggling to kick the butt

London: Singer Ronnie Wood is struggling to quit smoking. The Rolling Stones guitarist, who has battled with drink and drug addiction in the past, had promised girlfriend Sally Humphreys he would kick the habit but he is finding it hard, reports a website.

"Ronnie has really tried to knock smoking on the head but it`s one sacrifice too far. He told Sally he was going to give it his best shot but it just wasn`t too be," said a source.

"He`s done amazingly well removing alcohol and drugs from his life and cigarettes are the only vice he has left," the source added.
