LOL! HUGH HEFNER SAY'S HE CAN'T TELL HIS GIRLFRIENDS APART! ALSO SAY'S KENDRA'S BABY WILL END UP @ THE MANSION!

Hugh Hefner has been blessed with three new very gorgeous blonde beauties — two of which are twins. But despite his romantic relationship with 19-year-olds Karissa and Kristina Shannon, the men’s magazine mogul admitted at the recent Playmate of the Year party at The Palms in Sin City that he still can’t really tell them apart.

"I have one little trick, one has a little mark," Hef said, motioning to his neck. "Other than that, I don’t know."

The 83-year-old — who is no doubt living a life beyond most male’s wildest dreams — is also getting ready to see his trials and tribulations on the big screen in an upcoming Brett Ratner flick. And who does Hef want to play him?

Robert Downey Jr. and I have talked about it, it’s a very real possibility," Hef added. "Downey’s a marvelous actor, I would be honored."

We caught up with the ultimate Playboy (and his three leading ladies of course) again last week at AFI’s Tribute to Michael Douglas where he was glowing about former flame Kendra Wilkinson’s recent pregnancy news.

"Kendra is going to be a good mommy, she’s growing up and Hank is going to be a very good influence on her. They are an ideal couple," Hef said. "I’m sure the baby will end up at the Mansion. We do have (lots of little bunnies). We have a lot of friends and second generation Playmates, so there are a lot of kids around the Mansion these days."

So does that mean the iconic Playboy Mansion is losing its rep as the abode of bad behavior?
