Holly Madison is joining the cast of "Dancing with the Stars." The blonde bombshell is to strut her stuff on the TV talent show, according to her former "Girls Next Door" star Bridget Marquardt who accidentally revealed the news on live TV last night.

She said Holly had always wanted to appear on the reality show, but was banned by their former boyfriend, Playboy founder Hugh Hefner.

Holly Madison had a "good chance" of marrying Hugh Hefner. The 82-year-old Playboy founder considered making his former girlfriend - who is now dating magician Criss Angel - his wife, but was put off by his previous bad experiences.

Hugh said: "It has to do with timing. I've been married twice. Those are not the happiest times of my life, and I just don't want to screw up another."

Hugh Hefner has another new girlfriend. The 82-year-old Playboy founder - who split with former girlfriends, "The Girls Next Door" stars Holly Madison, Bridget Marquardt and Kendra Wilkinson last October - has moved 22-year-old Crystal Harris into the Playboy Mansion.

Crystal - who describes herself as a "good girl" who likes "the rain, the seasons and fast cars" on her MySpace page - shares the aging lothario with 19-year-old twins Karissa and Kristina Shannon.

Kendra Wilkinson hasn't flash her breasts since she got engaged. The former girlfriend of Playboy mogul Hugh Hefner has toned down her wild ways now that she is set to marry American football player Hank Baskett, according to her old housemate Bridget Marquardt.

She said: "Kendra is a lot more timely. She doesn't flash anymore. She's a lot more conservative. She's so in love. She's doing amazing."
