Recent rumours have it that Olsen twins, Mary-Kate and Ashley, are not seeing eye to eye on a cosmetic surgery issue.

The twins, who have recently returned to the spotlight to promote their new book, Influence, are said to be arguing over breast implants. It is understood that Ashley is considering having her breasts augmented and is attempting to persuade her sister to have surgery at the same time so that it is not so obvious that she has had cosmetic surgery.
