Those curious about whether Kendra Wilkinson, 29, actually had a physical relationship with Hugh Hefner, 88, during her time as one of his girlfriends living in the Playboy Mansion starting in 2004 need not wonder anymore.

Kendra, who is currently competing on the British reality series I'm a Celebrity, Get Me Out Of Here!, answers the very personal question point-blank in a recent episode.

"Are you obligated to sleep with him?," model Melani Sykes asks her as Kendra gets to know her fellow competitors in an Australian jungle.

"I moved in, and weeks went by, and I didn't know 'sex' was involved ... because I knew nothing about Playboy -- I had just graduated high school," she explains about first moving into the Playboy Mansion. "It's just like, 'Do you want to come upstairs?' And it's like, 'Sure, let's have fun.'"

"He really looks at them as relationships, as real relationships," she adds when asked if she would be thrown out if she refused to have sex with him.

"Do they all sleep with him at once?" another competitor asks about his multiple girlfriends.

"Yeah," Kendra says simply.

Kendra, who says she was 18 when she first moved in to the Playboy Mansion while Hefner was 78, rose to fame on E!'s reality series The Girls Next Door, which aired from 2005 to 2010. The series focused on the lives of Hefner's girlfriends who lived with him at the Playboy Mansion, including Holly Madison and Bridget Marquardt.

Kendra has no regrets about her Playboy past.

"I just wanted to party," she says about her initial motives to moving in. "And I had a damn good time. It was so much fun. Hef asked me to be one of his girlfriends and live in the mansion and I was like, 'I don't even know what that means but, hell yeah, I'm there.' I was living in a small ass apartment, with this ugly ass [bleep]. I was praying for anything to get me out of there."

Kendra is now of course married with two children to former NFL star Hank Baskett, although their relationship recently underwent a rough patch after rumors surfaced of his alleged affair with a transgender model.

“All I can say is I believe Hank," she told Us Weekly about choosing to stay with him. "I love Hank. And he’s proven to me that he's worth forgiving and fighting for. He was at the wrong place at the wrong time, and unfortunate things took place. He's very gullible and naive."

Hefner, meanwhile, has been married to model Crystal Harris since New Year's Eve 2012, after she initially broke off their engagement five days before their scheduled nuptials.
