Nicole Kidman Breast Implants: Actress Reportedly Went Under The Knife For Breast Augmentation

Nicole Kidman has reportedly gone under the knife for bigger breasts.

During an appearance at the Swisse Celebrate Life Ball last week, the actress and wife of country star Keith Urban appeared to be sporting a larger chest, which has led a couple of doctors to suspect that she recently underwent a breast augmentation.

“It appears she has had a pretty impressive breast augmentation,” Dr. Anthony Youn, who has not worked with Kidman, told Radar Online. “I suspect that she’s gone from a big a or small B to a full C [cup size]."

Although Kidman has admitted to having Botox in the past, she has always appeared to be naturally smaller in the chest. Even in low-cut gowns, such as the one she wore to the premiere of Zulu in May 2013, Kidman seemed fairly flat-chested. However, in photos from the Life Ball, which took place in Australia on June 13, Kidman is sporting tons of cleavage -- and it doesn't look completely natural. In fact, her chest seems a bit stiff.

Dr. Fred Pescatore, author of The Hamptons Diet, also believes Kidman recently went under the knife, explaining to Radar, “She hasn’t aged that much or gotten heavy so I feel they look like nice small implants."

“Overall I think it looks good, although maybe a touch overdone," Dr. Youn added. "It’s also possible she still has some swelling.”

So far, Kidman has not commented on the report.
