Kendra Wilkinson-Baskett talked to one of her I’m a Celebrity, Get Me Out of Here! cast-mates about her sex life with her former boyfriend, Hugh Hefner.

Now a married mother of two, she admitted she “didn’t know sex was involved” in the duties of being the Playboy founder’s girlfriend.

"I moved in and weeks went by and I didn't know that sex was involved," she said of moving in in 2003. "I knew nothing about Playboy, I'd just graduated high school."

E! Online reports when British TV presenter Melanie Sykes asked how it even came up in conversation, she explained "He was like, 'Do you want to come upstairs?' And I was 'Sure, let's have fun.'"

She was 18 and he was 78 at the time. However, she said she “wasn’t obligated to” sleep with him, it was her “choice.”

The Mirror reports she also talked about the state of her marriage to Hank Baskett, saying “I’m happy now.”

Her reality show, Kendra On Top, documents the aftermath of their cheating scandal – which dealt with rumors surrounding Baskett having an affair with a transsexual model.
