And two more bunnies move out of the Playboy Mansion: Hugh Hefner has split from two of his girlfriends.

The Playboy founder’s relationship with Crystal Harris has been “getting more serious,” so he has asked 20-year-old twins Kristina and Karissa Shannon to move out of the Playboy Mansion into the neighboring Playmate House. Speaking about suggesting the move to them, Hugh said, “When they thought about it, they thought it was a good idea. They will now be friends, but they won’t be defined as the girlfriends. They’ve been hanging out with a lot of the other Playmates and they see these girls traveling across the country to do promotion. They would like to be doing that, too.”

While the 83-year-old media mogul - who has been married three times - is happy with 23-year-old Crystal, he is adamant he won’t be making her his wife. “I haven’t had a lot of luck with marriage. I don’t have a good track record and I don’t want to screw this one up.”

Hugh is adamant the changes in his love life do not mean the end of reality TV show Girls Next Door, which documents life in the Playboy Mansion: “We’ll see how my relationships are changing romantically and how that relates to Crystal.”
