Actor Jamie Bell has taken to Twitter.com to urge reporters for a British tabloid newspaper to stop harassing his mum.

The Billy Elliot star, who is married to actress Evan Rachel Wood, appears to be mad that a reporter from the Daily Mail is trying to persuade Bell's mother to chat about her famous son.

He writes, "Dear Daily Mail journalist harassing my mother daily on her doorstep. She won't accept your money. She won't give you a story. Go away. Thx (thanks)."

News outlets have been trying to land an expose about the private couple, who became first-time parents last year (13), ever since they wed in 2012.
