Clear-skinned Zellweger's pics prompt talk of Surgical help

Doctor's hand with scalpelA full-faced and clear-skinned Renee Zellweger sparked lots of speculation over whether she had undergone Cosmetic Surgery after her appearance at a San Francisco charity event this week. Photographed in the full glare of podium lights at the 'do', the 35-year-old Bridget Jones' Diary star's flawless complexion – as well as the look of her brow bones and lips – prompted celebrity gossip website TheGloss.com to speculate over how she had managed to change her appearance.Writing on the site, Samantha Escobar said: "I saw the photo labeled Renee Zellweger [and] was genuinely perplexed. Girl looks different." (sic). "It's not as though she doesn't look lovely ... but I am so confused about how different she looks. Her eyes have a very different shape, as do her brow bones and lips." Ms Escobar added: "But even with stars, relatives and acquaintances whom I see photos of from five decades prior, I can still recognise them. I am just a little taken aback at how genuinely unconvinced I was of the caption “Renee Zellweger.” - Take a look at the pictures yourself – do you think Renee has had Cosmetic Surgery?
