The former Playboy model, now 39, was the youngest of the magazine mogul’s three girlfriends featured on their reality show, The Girls Next Door.

At the time, Hefner was also dating Bridget Marquardt, now 51, and main girlfriend Holly Madison, now 45.

Wilkinson had met Hefner at his 78th birthday party when she was just 18 years old, where she had been working as a ‘painted lady’, which involved her being nude except for body paint.

She moved into the Playboy Mansion shortly after they met in 2004, and went on to remain living there until 2009.

Many of Hefner’s former girlfriends have spoken out about their experiences at the mansion, and Wilkinson has now shared how it still affects her sexual relationships.

Speaking on the Amy & T.J. podcast, Wilkinson admitted: “Look, I struggle still to this day with my relationships and my views on sex.

“I had to go through a lot of therapy, and they looked at me and they’re like — this is the first time I’m admitting this — but they’re like, ‘You might have a little bit of a sex problem. You have a little bit of a problem when it comes to thinking of sex.'”

Host T.J. Holmes asked the model-turned-real-estate agent how her relationship with Hefner – and their 60-year age-gap – as well as the “environment” she spent those formative years in affected her long-term.

He asked: “Again, you’re a teenager. You hadn’t been necessarily exposed to healthy relationships at that point in your life, but it puts you on a certain path — what did that do to you and [how did it] shape what you thought a relationship was, should be, and the type of person you were interested in?”

Wilkinson admitted it caused her to have “just unhealthy thoughts”, explaining: “Not really settling for a marriage and stuff like that.

“Which is not, I wouldn’t say unhealthy — I’m saying that everyone has their choices, and some people wanna be single, some people wanna be married … and I’m more of a fun idea type of person.”

Wilkinson ended up leaving the mansion for good in 2009 after getting engaged to former Philadelphia Eagles star Hank Baskett, with the pair even holding their wedding ceremony at the Playboy Mansion.

She revealed that after five years at the notorious property, she was ready to move on with her life, telling Holmes and co-host Amy Robach: “I found myself so bored at the Playboy Mansion.

“I was just like, ‘I’m ready to leave this place. I’m ready to start a family. I’m ready for the lifestyle: My kids go to a great school. I’m a soccer mom. I’m a softball mom. I’m a basketball mom.’

“I manifested it, and it came to me, and I met the perfect man, the man of my dreams.”

Though she and Baskett ended up divorcing in 2018, she still recalls those times as “the golden years” of being a wife and a mother.

She admitted: “When those days came to an end, I crumbled so hard and it almost killed me. It almost killed me.”

Despite their break-up being sparked by cheating allegations, Wilkinson and Baskett have managed to maintain a great relationship as co-parents.

She explained: “Even though we’re divorced, he’s the father of my kids and he’s the most amazing father to my kids, and I know I chose right with him.”
