Kidman’s appearance at Cannes had people wondering what she did to her face

Her new film Grace of Monaco has been savaged by critics as it opened the Cannes Film Festival today (Wednesday) .

But it’s not just the biopic about the movie-star-turned-princess Grace Kelly that is attracting attention — also the film’s star, Nicole Kidman’s oddly puffy face.

The 46-year-old sparked more plastic surgery rumors while promoting the flick.

Despite proclaiming she has only dabbled once in Botox, leading cosmetic surgeon, Dr. Constantino Mendieta, says it is evident that the actress has had more work done.

“This is a classic case of when a beautiful woman goes too far with something that is supposed to enhance your beauty not change it,” he tells CelebZter. “It looks like Nicole has had too much filler injected in her face, either fat or some of the hyaluronic acids. Her cheeks are obviously overdone and her mandible is wider from the fillers.”

Last year, the mom-of-two told Italian newspaper La Repubblica she would never have surgery.

“No surgery for me; I did try Botox, unfortunately, but I got out of it and now I can finally move my face again,” she said.

What a difference a year makes: Kidman in 2013 at Cannes, where she showed the signs of aging around her eyes

Meanwhile, initial reviews of Kidman’s film have been scathing.

Peter Bradshaw of The Guardian writes: “It’s traditional for Cannes to start with something spectacular. This is certainly no exception. It is a film so awe-inspiringly wooden that it is basically a fire risk.

“The cringe factor is ionospherically high. A fleet of ambulances may have to be stationed outside the Palais to take tuxed audiences to hospital afterwards to have their toes uncurled under general anaesthetic.”

While Stephen Dalton of The Hollywood Reporter says that “the Shrek movies deconstruct fairy tale conventions with much more depth and wit than this dreary parade of lifeless celebrity waxworks.”
