Mary-Kate Olsen Ashley Olsen Playboy Magazine

In addition to courting a Marilyn Monroe-inspired centerfold with actress Lindsay Lohan, Hugh Hefner is hoping to snag a sizzling Playboy Magazine pictorial with twins Mary-Kate and Ashley Olsen in celebration of the pair’s twenty-second birthday in June.

“Hef thinks the twins are every young man’s fantasy,” a Star Magazine source spills.

But snitches close to Mary-Kate and Ashley, who will release their first book, entitled Influence, later this year, say that for now Hugh’s Olsen Playboy dreams will remain a “fantasy.”

“They’re all about high-end fashion these days. They want to do Vogue.”
