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.

Kim surprised many when she told Oprah Winfrey in 2012 about her mother's role in her first sexual experience when she was almost 15 and her mother agreed to put her on birth control.
She explained that the decision came as a result of her desire to lose her virginity to her boyfriend of two years.
"When I did want to have sex for the first time I was almost 15. 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."
