‘Girls Next Door’ Bridget Marquardt leaving Playboy Mansion

Looks like Hugh Hefner is all out of “Girls Next Door.”

Bridget Marquardt, the Playboy founder’s lone girlfriend to survive last month’s Mansion shake-up, is hinting that she’s on her way out.

“I don’t know how much longer I’ll be there,” the 35-year-old told Us Weekly.

Fellow “Girls Next Door” stars and recent Hefner exes Holly Madison and Kendra Wilkinson are “moving out right now,” she added.

Madison and Wilkinson announced their respective splits from Hefner last month, and were quickly replaced by 19-year-old twins Karissa and Kristina Shannon as the objects of the octogenarian’s affection.

Marquardt was out of the country during the fall-out, and resurfaced just last week for a Playboy Halloween party.

“I’ve been doing a Travel Channel show,” she said. “To be honest, I’m not even [at the Mansion] that much at the moment anyway.”

Despite the impending split, Marquardt still appears to be in Hefner’s good graces: The buxom blond joined Madison and Wilkinson Thursday night at New York’s Hotel on Rivington for the launch of a new men’s cologne for Playboy.

Madison, Hef’s former No. 1 girl, has since moved on with magician Criss Angel, her partner in PDA at the “Criss Angel Believe” premiere in Las Vegas on Friday; Wilkinson is now dating Philadelphia Eagles wide receiver Hank Baskett.

The Shannon twins have been mostly silent since moving into the Mansion, but recently updated their MySpace page to thank their fans “for all the love.”
