Kirstie began the discussion by opening up about having sex in the back of a car after picking up her friend from the airport.
Speaking in a preview clip from tonight’s Celebrity Big Brother, she dished: “I was filming a movie and there was a woman, i don’t believe in furs, but she had this amazing sable fur that fell to the floor and I was like would you mind if I wore this to something?
“And I was naked underneath and I picked my friend up at the airport and then I asked the chauffeur, ‘Could you please close the windows?’
“It was fun just because, you know I’ve read about that sort of thing so I wanted to do it.”
Her tale shocked both Roxanne and Sally, who went on to share details of their own romances.
Sally confessed of her relationship: “When we first met, we couldn’t keep our hands off each other.”
“That’s what I’m saying, but for how long?” Kirstie asked.
Sally replied: “I would say for the first 25 years. I didn’t want anyone else.”
Kirstie was momentarily stunned before she shared: “I didn’t want anyone else either but I was more interested in watching [Jimmy] Kimmel.”
“He obviously wasn’t satisfying you,” Sally calmly noted.
Kirstie continued: “For me, three times a week is plenty. I don’t want to have sex seven days a week.”
“You can’t help it, Lee smells amazing,” Roxanne said jumping into the conversation.
Kirstie hit back: “But that’s young love.”
“He could do anything and I would just think aaaah,” Roxanne continued.
“My nipples get hard just talking about him.”
Also in tonight’s episode, Roxanne, Gabby Allen and Chloe Ayling will strip down to their lingerie for a task.
Following instructions from Kirstie, they will rub whipped cream on their chests and dance for the Big Brother eye.
The boys can be seen standing outside the living room watching on.
The girls appear to be successful with the task they have been set – how will they be rewarded?
Celebrity Big Brother continues tonight on Channel 5 at 9pm.
