As she enters her 39th year, Khloé is focused on raising her two kids, daughter True Thompson, 5, and son Tatum Thompson, 11 months, whom she shares with ex Tristan Thompson.  She’s also the founder of denim brand Good American, and of course, appears on her family's reality show, The Kardashians, which airs on Hulu.

On a recent episode of the show, Khloé explained that has no desire for a romantic rekindling with Tristan, though she remains on good terms with the father of her children.

"Him and I have a great friendship relationship, we get along fine, and for my kids, I will put anything to the side," she said. "What's done is done, so what would I still be holding on to something for? I don’t need to 'punish' him because I'm not getting back with him."

She also noted that "there's still boundaries" between them and that she is "definitely putting my foot down around a lot of things."

"We’ve done this song and dance a handful of times already. I've gotten back with him after a cheating scandal so I don't know if Tristan is under the impression, 'Oh wow, OK, let's just ride this out and eventually she’ll get back with me,'" she said. "I get why he would think that, so it's my job to set boundaries that my actions show otherwise. I keep it very short and sweet and make sure he knows it's always about the kids because it's so easy to fall back into [habits]. I can't let those old habits easily come into my life. It's just not what I want."
