Ronnie Wood's ex-wife Jo is keeping her upcoming autobiography a secret from the Rolling Stones rocker.

The couple split in 2008 after 24 years of marriage following his affair with Russian waitress Ekaterina Ivanova.

Their divorce was finalised in 2011, and now Jo Wood, who has two children with the guitarist, is preparing to lift the lid on her life with the musician in a tell-all tome.

Despite the book being almost completed, Jo admits she has failed to warn her former husband about the memoir.

She tells Britain's Daily Mail, "I've just finished writing my autobiography. I haven't told Ronnie about it. It kind of slipped my mind! I saw him the other day, and I thought "Oh no, I can't tell him now". I might wait for him to find out in another way! No, I should tell him. I will tell him soon.

"I found a great ghostwriter who I absolutely adore and we've had a look of fun writing it. It's very funny actually. I've got lots of funny stories you see! I really enjoyed doing it."
