Hugh Hefner is certainly not lonely. The old dude has three new girlfriends living at the Play boy Morrison and supposedly another lady is hanging out…  Hugh’s wife, Kimberly Conrad! Read more on Hugh Hefner and Kimberly Conrad below.

FoxNews.com reported that Hugh Hefner’s estranged wife, Kimberly Conrad, has been visiting much more frequently to the mansion.

Of course Kimberly Conrad regularly dropping in for the bunny-free Tuesday “family nights,” but she’s recently added the gal-pal-friendly movie nights to her schedule too. So could Hefner and Conrad be planning to get back together?

Kimberly Conrad and Hefner married in 1989, which she the year Conrad was crowned Play mate of the year?Conrad and Hefner have two sons together, Marston, 18, and Cooper, 17. The couple did separate back in 1999, but never officially divorced.

The divorce issue was one that didn’t go over too well with Hugh’s former main girlfriend, Holly Madison.  Madison recently left the Morrison and is now datihugh-hefnerng Criss Angel.  Madison’s fellow “Girls Next Door” stars Kendra Wilkinson and Bridget Marquardt also left the mansion soon after. And then here came three new girlfriends: Crystal Harris and twins Karissa and Kristina Shannon, who now live with Hefner.

It’s being reported that Crystal Harris recently knocked the bad-girl twins from the master bedroom and has been promoted to Hefner’s number-one girlfriend.

“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.”

So do you think Hefner has finally grown up and wants to get back with Kimberly Conrad now that Holly Madison is out of the picture?
