Nicole Kidman's Boobs Look HUGE – Plus See 6 Stars Who Seem to Have Gotten Surgery But Denied It - In Touch Weekly

Besides looking happy hand-in-hand with her husband Keith Urban, there was something noticeably different about Nicole Kidman on the red carpet—her boobs!

While attending the Celebrate Life Ball in Melbourne, Australia on June 13, the Grace of Monaco star wore a low-cut revealing dress that accentuated her chest. Even though the gown was gorgeous, her boobs stole the spotlight.

Just last month at the 67th Annual Cannes Film Festival (pictured below left), Nicole's chest is clearly not as big.

This leads us to the question: Did Nicole Kidman have a boob job?!

"Famously flat chested, Nicole's boobs certainly look they've had a boost," Laura Casewell, editor of the Cosmetic Surgery Guide, tells the Daily Mirror. "They not only look bigger but also much more rounded, which indicates she's had breast implants."

The 46-year-old actress has yet to make a statement. However, these six stars have either denied or refused to comment about their increased chest size.

“I’ve had none [plastic surgery]. But you know, my boobs are real…People have said that I’ve had things like a jaw replacement or implant or something," Jessica said about being au naturel. "I’m photographed every day of my life and have never worn bandages or anything, so how could that be right?”

“I don't like to talk about that,” The Hills alum said when asked about getting a boob job. "Well, see I have this chest problem. My bone right here, it's higher on this side? It's pectoralis something. So I've always struggled with that. You could see they look different sizes all the time.”
