Keeping it in the family? Khloé Kardashian revealed if she would date someone her sisters had been with in the past.

“OK, he’s the best sex you’ve ever had, but you find out he once hooked up with one of your sisters,” Alex Cooper proposed during the Wednesday, April 16, episode of the “Call Her Daddy” podcast.

Khloé, 40, didn’t miss a beat with her response.

“You want to know what’s crazy? The older we get, the pool gets smaller,” the Good American founder replied. “I don’t know. I think if I was 20, I would probably be like, ‘That’s a deal-breaker,’ but now I’m like, ‘Do we need to talk about it? We’re good, right?’ I don’t know. Is that incestual?”

When Alex, 30, pointed out it might be a little questionable to hook up with someone who has a child with one of her siblings, Khloé clarified that’s where she would “draw the line.”

The mom of two continued, “We’re not sharing baby daddies, but I don’t know, if you slept with someone 20 years ago, what the f–k am I supposed to do? It’s hard out here. I wouldn’t care if it was me. Let’s say Kim [Kardashian] or whoever was single was like, “Oh, I met this guy,’ and I’m like, ‘Oh my God, I f–ked him when I was 20, but it’s fine.’ I wouldn’t care.”

Khloé also opened up about her ex Tristan Thompson’s multiple cheating scandals and what she considered to be the worst part of the situation.

“I think the worst part of that experience was how much I let down my younger sisters,” Khloé told Alex. “I remember they were like, ‘He’s going to do this again, don’t stay with him.’ I don’t know exactly what was said, but I just remember the disappointment in them. I’ve always felt how much I’ve disappointed them by staying and doing that again.”

Khloé revealed that Kim, 44, actually found out about Tristan’s cheating scandal before she did.

“When Kim found out that Tristan was cheating on me when I was pregnant, she was, if I remember correctly, I think she was about to sit down for Keeping Up interviews, and it happened while she was in the interview chair,” Khloé told Alex. “I don’t know if as much would have been shown if that’s not how it was unfolding in real time. We just happened to be filming all the f–king time, so it did happen that way.”

Khloé and Tristan, 34, began dating in 2016, and the following year, The Kardashians star announced she was pregnant with her first child.

“My greatest dream realized! We are having a baby! I had been waiting and wondering but God had a plan all along. He knew what He was doing,” Khloé wrote via Instagram on December 20, 2017.

However, just days before Khloé was set to give birth, news broke that Tristan had cheated on her when video footage surfaced that showed him making out with another woman. Khloé and Tristan later welcomed baby No. 2 via surrogate. Their son, Tatum, was born on July 28, 2022.
