She's still got it!

25 years after starring in Olay's original UK TV ad campaign, iconic Sixties model Twiggy is back to work as the brand's face, this time appearing in Olay Definity's new UK print ads (above).

"We we thrilled to welcome Twiggy back to the brand," says Sarah Clarke, spokesperson for Olay Definity. "She is a true beauty icon who continues to be an inspiration to millions of women across the UK."

Despite the controversy that her rail-like, boyish figure caused (you think Kate Moss had it bad?), the original waif (now, about to turn 60) has endeared herself to an audience of women who have likely long given up trying to look good in a Mary Quant minidress.

In addition to the new Olay campaign, the supermodel is continually the center of British behemoth Marks & Spencer's celebrated high-profile ad campaigns (holding her own with the likes of fresher-faced models like Lily Cole, Erin O' Connor and Lizzy Jagger), and even has her own line of apparel and bed linens.

Maybe it's Twiggy's down-to-earth attitude about aging that makes the former "It" girl so easy to relate to.

"I don't understand people getting depressed about growing older," she told the Daily Mail. "There is nothing you can do about it, so you might as well embrace it."
