SO WRINKLES PROVE WISDOM?: Leighton Meester claims to have no fear when it comes to aging, but ask her again in a few years — after all, she’s only 23. Regardless, Meester gets a preview of her own aging process in the September issue of Harper’s Bazaar, in which editors have produced digitally enhanced images of the actress to show what she’d look like into her 20s, 30s, 40s and 50s. The “Gossip Girl” star is also on the cover, shot by Terry Richardson. “Any fear of aging, I think, is simply vanity,” Meester told the magazine. “Because what comes with age is so many wonderful things: wisdom, understanding.

“Every year, I’m always happy to be done with the previous age,” she says, adding she does support Botox. “If people want that, do it.”

Along those lines, Harper’s Bazaar is also launching a nationwide contest to find America’s chicest women, from age 20 to over 60. Five finalists, representing each decade between 20 and 60, will win a cash prize of $5,000 and appear in a future issue, along with a party at Hearst Tower. The contest is also a prelude to the magazine’s upcoming book, “Fabulous at Every Age: Your Quick and Easy Guide to Fashion,” in stores in November. — A.W.
