Rod Stewart's ex-wife Rachel Hunter is considering undergoing cosmetic surgery to maintain her beauty into middle age. The 36-year-old - who has two children LIAM, 12, and RENEE, 14, with the MAGGIE MAY rocker - will stay natural for the remainder of her thirties, but is planning to keep wrinkles at bay by turning to botox in her forties. The New Zealand-born model says, "There's nothing wrong with surgery if you want to get something fixed. Just don't do it for anyone except yourself. "I've never had botox but I've contemplated it and I probably will have some done. But not yet. Where do you go after a face-lift at 30?"
