As you may be wondering and dying to know, Kim Kardashian and Hailey Bieber are both members of the Mile High Club. Bieber said that she and Kardashian are "old friends" and that she is not surprised that the SKIMS founder is a member, People reports.

During their conversation, Bieber suggested that the two play a game of "Truth or Shots" in which they answer "spicy" questions or take shots if they don't want to spill. Bieber asked, "Have you ever been in the Mile High Club?" (The Mile High Club is, as "People" so cleverly put it, and for the rare person who doesn't know it, "an informal association of people who have had sex on airplanes while the plane is in the air.")

"Yes," Bieber quickly replied. Kardashian's reply was "Samesies." (Probably easier to pull off if you fly private or, you know, have your own plane *cough Kim*).

"I was going to say I don't have to ask that," Bieber said. Kardashian pretended to be offended and said, "Why, you don't have to ask that?"

"I said, 'I don't know.'

"You own a plane," Bieber said. Kardashian laughed, "Of course you're a whore."

The episode was filmed last August but not released until last week; the two also talked about growing up in L.A., described their mother, Kris Jenner, as their "secret room," and opened up about the celebrity friends who have blended into DMs.

"Who's the most surprising person who's ever walked into your DMs?" Kardashian asked Bieber. Kardashian asked Bieber.

"Honestly, I've seen it," Bieber said. 'Like in general, is anyone trying to hit on me or say anything weird? I've never been sneaked up on, even before I got married. I've never had anyone say, "This guy just blended into my DMs". I don't have any stories like that. I'm sure you don't."

Kardashian confirmed that she does indeed receive many DMs, but she does not respond: "A lot of people get into my DMs. I'm not going to lie. A lot of people are inappropriate."

"I'm not surprised," Bieber said.

"I just don't respond," Kardashian continued. 'Like I'm living my life. But let me tell you some things," she leaned over to Bieber and began whispering.

"Wow, that's bold," said a shocked Bieber.
