Nicole Kidman was once noted by US Magazine to have said she would never go under the knife, but her recent appearances on the premieres of "Grace of Monaco" in Shanghai and on a red carpet at the Swisse Celeberate Life Ball in Melbourne are raising speculations that she has undergone the knife and got a breast augmentation procedure done.

Kidman once told the press, "Kidman told press, "No surgery for me; I did try Botox, unfortunately, but I got out of it and now I can finally move my face again." However, experts are weighing on Kidman's most recent appearances and saying she had some procedures done on her bust to make them look fuller. In her thin frame, the boost in size is quite visible.

Last Thursday, June 12, Kidman appeared on a red carpet in a revealing Prada dress at the Swisse Celeberate Life Ball held in Melbourne. On June 16, Kidman pleased her Chinese fans by showing up on premieres of her new movie "Grace of Monaco" in Shanghai wearing a conservative black dress and matching sophisticated heels. On both accounts, many claimed her breasts appear larger.

Experts who have not treated Kidman themselves claim they can still see for themselves that the 46 year old actress has some procedures done on her bust. "It appears she has had a pretty impressive breast augmentation," Dr. Anthony Youn told Radar Online. "I suspect that she's gone from a big a or small B to a full C [cup size]."

The speculations were not made without basis. Even though Kidman admitted she had Botox last year, her body always look petite and slim. Even though she wore some revealing outfits over the years, her cleavage was not something anyone would take notice of for their size. However, her appearances lately are doing just that.

Dr. Fred Pescatore, the author of "The Hamptons Diet." who also hasn't treated Kidman, claimed to Radar that he thinks Keith Urban's wife has undergone the knife to make her breasts bigger, albeit not in a vulgar form. "She hasn't aged that much or gotten heavy so I feel they look like nice small implants."

Dr. Youn claimed that the implants, if Kidman did get some, are done nicely relatively. "Overall I think it looks good, although maybe a touch overdone. It's also possible she still has some swelling."
