AceShowbiz - Nicole Kidman, 57, has recently reignited rumors about possible cosmetic surgery due to a stark contrast in her appearance over the years. An old episode from her 2016 appearance on "The Graham Norton Show resurfaced over the weekend, causing buzz as fans noticed her look markedly differed from her earlier days as a model.

Graham Norton shared an old cover photo of Kidman from the Australian magazine Dolly, dating back to 1983. "You looked stunning on the cover of Dolly Magazine in 1983," Norton remarked, drawing an evidently uncomfortable reaction from Kidman, who cringed at the sight of her younger self.

Kidman seemingly explained why she looked different from her old self, "I have to say to anyone that has curly hair when you are young, keep it, don't straighten it. After awhile you don't get your curls back."

However, this wasn't enough to quell the curiosity of many fans and critics. The stark difference in Kidman's appearance from her teenage years to now has fueled speculation about potential cosmetic enhancements.

Social media has been rife with comments questioning her transformation. One user sardonically observed, "God, she is full of it! She was a redhead with freckles and now she isn't... but she doesn't use Botox!" Another added, "With all that Botox, I'm surprised she could move her face."

Kidman previously addressed these rumors in a 2007 interview with Marie Claire, asserting, "To be honest, I am completely natural. I wear sunscreen and I don't smoke. I take care of myself. I'm very proud to say that."

Nonetheless, in 2011, during an interview with the German magazine TV Movie, she admitted to having tried Botox but claimed she didn't like the effects, stating, "I even tried Botox but I didn't like how my face looked afterwards. Now I don't use it any more and I can move my forehead again."

Despite her open acknowledgment of Botox, the ongoing scrutiny and debates about her evolving appearance suggest a persistent public fascination with the beauty standards and pressures faced by Hollywood celebrities.

Nicole Kidman's forthcoming appearance on "The Graham Norton Show" is expected to be yet another instance where fans and spectators will be watching closely, not just for her insights and charming personality, but also to dissect her current look in comparison to the past.

As Kidman continues to navigate her illustrious career, the conversation around her appearance underscores wider issues of public perception and the unavoidable spotlight on stars' attempts to age gracefully.
