New York, Jan 14 : Soon after Hugh Hefner's ex-girlfriends Holly Madison, Kendra Wilkinson and Bridget Marquardt moved out of the Playboy mansion, the octogenarian mogul has opened doors of his love pad for his new playmates.

Hefner's new girlfriends Crystal Harris and Kristina and Karissa Shannon have officially moved into the mansion, confirmed his rep.

Late last week "Girls Next Door" star Marquardt announced that she has decided to leave the Mansion, following in the footsteps of Holly and Kendra and "become her own person."

Now, the mansion is home to the 19-year-old Shannon twins, who have become permanent accessories for their 82-year-old shared boyfriend.

And Hefner's third girlfriend, Harris, recently wrote on an E! message board over the holidays that the foursome are considering expanding their posse.

"There are a couple [girlfriends] that we have interest in. As for now, it is just us three," The New York Daily News quoted her as saying. (ANI)
