London: The latest Hollywood star to hit the headlines for going under the knife is Cameron Diaz. The Charlie's Angels star, 39, was spotted on a beach in Hawaii looking rather shapely, fueling rumours of a breast enlargement.

The active and fun-loving actress was found flaunting her bosom on a beach in Hawaii where she was vacationing.

Sporting a short hair do, Diaz is said to have had implants to increase her chest by a cup size, according to the National Enquirer.

Daily Mail quoted plastic surgeon Dr Anthony Youn, who has not treated the star saying, “I believe she has had a breast augmentation using relatively small silicone implants. Since swelling can take severely weeks to settle down, I suspect she had the surgery at least two to three weeks ago.”

In an interview to Marie Claire in 2009 this sexy star, who is said to have gone under the knife earlier also, said she would prefer a more curvy figure: “Love to be more voluptuous. It's just not my body type."

However, the star, who had her nose fixed in 2006 after breaking it four times, said in 2010 that she would rule out more surgery.
