Nicole Kidman used to be scrutinized for reportedly Botoxed forehead. Now it appears people are buzzing about her lips.

At Wednesday's Country Music Association Awards, "she looked freakish," a witness tells the New York Post's Page Six. "She just had her lips done, and now she looks like Meg Ryan."

In the past, Kidman, 42, has denied plastic surgery rumors.

"I am completely natural," she's said. "I have nothing in my face or anything."

But Dr Martin Braun -- who runs the biggest Botox clinic in Canada -- told a conference of medical experts in 2008 that the actress is so "over-Botoxed" that she's starting to look like a bat.

He added that the actress -- who has signed on to play Einar Wegener, the first post-operative transsexual, in the upcoming drama, The Danish Girl -- looks "frozen and strange" because of her extensive use of the anti-aging treatment.
