Reese Witherspoon is suing bosses of a jewellery website for using her image in promotional material without permission.

The actress' lawyers have filed suit against executives at Marketing Advantages International, a company which runs accessories and costume jewellery site Emitations.com.

In one online advert, an image of the Oscar winner posing with her hand to her face - showcasing a huge diamond ring, has been used.

The suit is seeking damages for exploiting Witherspoon's name in a bid to boost sales, according to Tmz.com.
