Khloe Kardashian reveals she will never let her daughter, True, have a sleepover at Kourtney Kardashian's home while strapped to a lie detector. As some wonder why the Good American founder would do that, fans start to make assumptions about what led her to that decision.

Khloe and Kourtney were featured on Vanity Fair's lie detector test web series on Thursday, December 15. Aside from that big sleepover revelation, Lamar Odom's ex also answered an intriguing question if she still sleeps with her baby daddy Tristan Thompson.

The Poosh Founder delivered the questions her sister had to answer and asked if she would ever let her four-year-old child spend a night at the Kardashian-Barker household. "Probably not," she simply said.

Though she didn't give any reason to defend her response, Travis Barker's wife once again asked her if it was because they "have too much fun." "No," Khloe stated again.

The mother of two then explained that they didn't have enough time to reveal the reason. Naturally, Scott Disick's ex-partner just moved on to another question, but fans started theorizing why Khloe would not let True sleep with her aunt and cousins Mason, 13, Penelope, 10, and Reign, 8.

One fan said, via Page Six, that it might be because there were no good snacks at Kourtney's home-all were sugar-free and gluten-free, knowing Kourtney and her kids are following a gluten- and dairy-free diet. Another claimed that her kids' misbehavior might have something to do with Khloe's decision, describing them as lacking respect for their nannies and parents.

If this netizen were Khloe, they would probably do the same. Lastly, one fan believed it might be because of the active sex life of Kourtney and her husband, Travis Barker. The two have been known for packing major PDA even in front of their kids.

In fact, at one point, her son, Reign, begged him and his stepdad to stop French kissing, telling them he would die. Her daughter, Penelope, alternatively, also asked them to tone down their smooching whenever she was around.

In addition, Kourtney couldn't help but grill Khloe more about her relationship status with Tristan. She asked if they were still sleeping together, to which Khloe stressed that she "really not."

The lie detector later confirmed her statement as true, making Khloe feel relieved. "I would die if it said I was," she stated.

Khloe and Tristan officially parted ways a year ago after having an off-and-on relationship following Maralee Nichold's paternity lawsuit. The latter claimed the Chicago Bulls player was her son's father, who later confirmed the appeal and apologized to his baby mama.
