Hugh Hefner’s next girlfriend? 

Already his wife?

Conrad’s no stranger around the house, regularly dropping in for the bunny-free Tuesday “family nights,” but she’s recently added the gal-pal-friendly movie nights to her schedule as well. Hmm, guess she’s not so estranged anymore.

Conrad and Hefner married in 1989, the same year she was crowned Playmate of the Year, and she is the mother of his two sons, Marston, 18, and Cooper, 17. The pair separated in 1999 but have never officially divorced - a sticking point for Hef’s ex, Holly Madison, who recently split from the magazine mogul.

Madison’s fellow “Girls Next Door” stars Kendra Wilkinson and Bridget Marquardt also hopped out of the mansion not long after , paving the way for three new girlfriends: Crystal Harris and twins Karissa and Kristina Shannon, all of whom now live with Hefner.

Good-girl Harris recently bumped the naughty twins from the master bedroom and has been promoted to number-one girlfriend, a spy tells FoxNews.  “Everyone was quite surprised when [Crystal] moved in. She’d just started coming to the Mansion for movie nights and BBQs but nothing romantic was going on then suddenly she was in,” said the snitch. “So far there is no jealously between the twins and Crystal, but we’ll see how long that lasts.”
