"Guys, I don't know what to do," she casually told the group. "I went number two in that bathroom and it won't flush."
Kim and Kourtney then burst into laughter.
"It's really embarrassing," Kim added, continuing to laugh. "I was going to blame it on Kendall [Jenner], I should have done that."
"I didn't even think you did that," Scott quipped.
It's unclear what ended up happening with the toilet as the group's conversation shifted to Kim giving Khloe advice about surrogacy.
Meanwhile, speaking of number twos, Kim threw her daughter, North West, a poop emoji-themed party for her 8th birthday earlier this month.
The SKIMS founder shared photos from the fun and uniquely decorated affair on her Instagram Story at the time. As shown from the photos, North and her friends received some epic party swag, including customized duffle bags with poop emoji patches on them and brown poop emoji onesies.
"Poop Diddy Scoop kinda slumber party," Kim wrote alongside a photo of North and her friends wearing the matching onesies. The caption was a reference to the lyrics of Kanye West's song "Lift Yourself."
Kim -- who shares North as well as Saint, 5, Chicago, 3, and Psalm, 2, with Kanye -- also posted a sweet tribute to North on her birthday, June 15.
"My 1st born baby North is 8 years old today! North, one day you will see these messages all printed out for you in the books I am making for you and so hope you feel the love because you bring so much love and joy into all of our lives!" she captioned a series of photos of herself with her daughter from a Jacqueline Kennedy photoshoot, below. "You are the silliest, most stylish, most creative person who knows exactly what they want in life! I've never met anyone like you!"
Kim continued, "I picked these BTS to post of North and I from this Steven Klein Jackie O shoot bc it just reminded me of the bond North and I share and he always captures the emotion so well!"
