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.

Mary-Kate has been rumoured to have refuted the idea, leaving Ashley with a dilemma – should she get the breast implants and end up looking a lot more curvier than her sister, thereby announcing to the world she has had cosmetic surgery, or should she stay the way she is.
