Khloé Kardashian opened up about the fate of her last relationship with NBA player James Harden during this weeks' episode of her hit late night FYI talk show "Kocktails with Khloé" and revealed that she dumped Harden because of his infidelity. However, Kardashian also spoke candidly about her mother Kris Jenner's affair and how it affected her father, the late attorney Robert Kardashian.

On the Wednesday night episode of her new series, the reality star answered truthfully when her guest, "The Real Housewives of Beverly Hills" star Lisa Rinna, asked Kardashian why she ended her relationship with the Houston Rocket.

"He sought me out, he wanted to be committed and then [he] wasn't committed, so KoKo had to let him go-go," Kardashian said. "I got the receipts to prove it."

Rinna admitted that she thought Kardashian would have been the one to be unfaithful during her relationship with Harden, but Kardashian said that she has never cheated during any of her past relationships and gave her heartfelt explanation.

"Love my mom, but my mom cheated on my dad, she's been honest about it," Kardashian revealed. "But I think because of that, and I saw how it like destroyed my dad, I've never ever cheated in any relationship."

"I just believe in being honest and even if you're not feeling something-you don't even have to want to cheat, if you're just not fully invested in a relationship, I believe in being honest about that," Kardashian continued. "I won't say 'I love you' if I don't mean it, I just don't believe in...I just saw what it did to my dad and I was like I don't wanna do that. But I appreciate that, those lessons and I also saw the regret from my mom. So I've never ever cheated in my life, I don't believe it needs to be done."

Jenner wrote about her 1989 affair with then-professional soccer player Todd Waterman in her 2011 memoir "Kris Jenner and All Things Kardashian," which led to her divorce from the high-powered lawyer. Jenner said in an interview last month that divorcing Robert was her only regret. "I had a wonderful, beautiful life with Robert. He was just an amazing man," Jenner told Harper's Bazaar. "I always wish I could call Robert right now. That's an everyday thing."
