Looking sensational in Chanel, Demi Moore was on a Big Apple blitz for her new diamond heist thriller, "Flawless," - and she talked exclusively to "Extra" about hubby Ashton Kutcher's ultra-revealing underwear pose in V Man magazine. "I love them," she said of the hot pics. "But I don't need to see the picture -- I get to see it everyday!" Some gals have all the luck!

Demi hit last night's after-party with 14-year-old daughter Tallulah and ex hubby Bruce Willis with date Emma Hemming. Demi said of her upcoming Ashton anniversary, "He asked me to marry him on April Fools' Day. It didn't turn out to be a joke, though -- we're five years going." The brunette beauty also told "Extra" that Ashton was pulling his famous "Punk'd" stunts on the "Flawless" set, saying, "Let's just say there was some stinky cheese left in a few interesting places!"

The mother of three looks especially gorgeous these days, but the secret to her healthy glow may leave her fans bugging out. Demi revealed on last night's "Late Show with David Letterman" that she uses leeches to detoxify her blood. "It detoxifies your blood and they have a little enzyme that when they're biting down on you gets released into your blood," she explained. "It crawls in and you feel it bite down on you... and then you just watch it swell up and get fatter and fatter and then when it's super drunk on your blood it just kind of rolls over like it's stumbling out of a bar." This is one cosmetic secret that doesn't seem likely to catch on.
