Kim has previously talked of spending her 14th birthday at Jackson’s Neverland ranch.

‘When you drove up, there were baby elephants and chimpanzees in overalls, and there was all the rides. It was everything you can possibly imagine,’ she previously told People magazine. 

And speaking about Kim last year, TJ, who is married with three children, told Britain’s Reveal magazine: ‘I still talk to the family every now and then, though not too much because our schedules are pretty busy.

‘I dated Kim when my mother passed away, so I was actually quite close to the family when I was young.’

She explained that the decision came as a result of her desire to lose her virginity to her boyfriend of two years.

Kim said: ‘When I did want to have sex for the first time I was almost 15’, adding her liberal mom was open to discussion about the topic.

She continued: ‘I was like, “I think I’m going to, or I want to,” and she was like, “OK, so this is what we’re gonna do, we’re gonna put you on birth control,” and she was like, really open and honest with me.’

After her two year romance with TJ, Kim went on to have several high profile relationships with a slew of famous faces, including Ray J – with whom she famously made a sex tape – and NFL star Reggie bush.
