Hugh Hefner admits even he can't tell apart his twin girlfriends Karissa and Kristina Shannon, "I have one little trick, one has a little mark (on her neck), other than that, I don't know," he tells Fox News.

And what does Hef have to say about his ex and former 'Girl Next Door' Kendra Wilkinson getting pregnant? "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. 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."

And Kendra's fiance Hank Baskett agrees, telling E! Online, "Hef will definitely be involved with the baby. Hef is a great man, and I know there is more to his and Kendra's relationship than people see and actually know. I see it every time they're together. Hef will be a part of the baby's life. That's one of the first things we want to do is bring the baby out here to California and let Hef be introduced. I can see The Godfather being a good name for Hef!"

And now that Kendra is going to be a Mom, does that mean no more naked Playboy appearances? "You know, that's a question that will get answered if that comes about," said Hank. "I don't really see her wanting to do any more Playboy, but like I said, that's a decision that will be made if that comes up. We'll cross that bridge when we come to it!
