Hugh Hefner insists he is still dating Holly Madison. The magazine mogul - who currently lives with his three girlfriends Holly, Kendra Wilkinson and Bridget Marquardt in the Playboy mansion in Los Angeles - has denied claims all his relationships are on the rocks, but has hinted he may not always be able to make main girlfriend Holly happy.

He said: "I love Holly very much, but she wants very much to get married and have children. That isn't on the cards for me. So there has to be a certain reality there. And I'm sure the time will come when she'll be dating others. That's part of the transition."

Holly was spotted getting close to magician Criss Angel on a recent night out in Las Vegas, and although she has stopped short of admitting her relationship with Hugh is struggling, she is yearning for a more stable lifestyle. Referring to Hugh's relationship with Kimberley Conrad, 45, to whom he is still legally married, Holly said: "I want to be with somebody who I can be married to, and have kids."

Hugh, 82, is unimpressed with rumours Holly is getting close to Criss, saying: "One hopes that when she starts dating, she'll have better taste." Meanwhile, Kendra has been romantically linked to American football player Hank Baskett.
