Los Angeles, California - Khloé Kardashian and Kourtney Kardashian spilled some serious tea as they got brutally honest about their other sisters, love lives, and their hot takes.

The reality star sisters were candid with one another while taking a lie detector test with Vanity Fair.

Things got awkward quickly when Kourtney asked Khloé about her honest opinion on her lavish Italian wedding to Travis Barker.

While Khloé truthfully told her sister that she had fun at the wedding, she got caught in a lie when asked if she liked Kourt's custom-made wedding dress.

"It was fine," the 38-year-old answered, which the examiner declared as "inconclusive" on the polygraph.

"I mean, it was beautiful for sure. I just would've loved to see you in that at the after-party and then something prior," Khloé admitted.

When it was Kourtney's turn, the 43-year-old bizarrely confessed to keeping a strand of her son Reign's hair in a safe. She also proved just how little she keeps up with the news (as she loves to remind everyone) when she failed to recognize a photo of Jeff Bezos.

These odd confessions were not all, as the sisters also divulged some juicy details about their respective love lives.

Both sisters were willing to be upfront about the details of their love lives.

Kourtney almost certainly shared more than fans ever wanted to know as she dished about her hubby.

The Poosh founder admitted to having been caught having sex with him in public, as well as hooking up while donning their Halloween costumes in 2021.

Khloé, meanwhile, was grilled about her infamously toxic ex, Tristan Thompson.

"Oh, are you still sleeping with Tristan?" Kourtney asked.

The Good American owner quickly shut it down, saying, "No, I am not. I'm really not."

When the examiner confirmed she was telling the truth, Khloé joked, "I would die if it said I was [lying]!"

At least now, fans can finally put the endless speculation about the pair to rest.
