Kim Kardashian REFUSES To Divulge Celebrity Crush To Hailey Bieber

Kim Kardashian certainly plays her cards close to her chest, even if Hailey Bieber tries to dig the information out, as is clear from Bieber's YouTube show, "Who's in My Bathroom?"

Here's what went down in Hailey Bieber's bathroom, including ice cream sundaes!

While making sundaes in a bathroom sounds gross, Hailey Bieber's bathroom can fit in a whole house, and they even managed to impress Kim, which has to be a feat in itself.

After making a "KimK Special" sundae which consisted of choco chip cookie dough ice cream with caramel, peanut butter M&Ms, Oreos, and dibs. We second Hailey Bieber's "Yum!"

Over ice cream, the two connected over skincare and how Bieber reached out to her when she had the idea to launch her brand, Rhode. The supermodel, 26, told the reality star, 42, that she was the "first person" she turned to, saying, "I remember, at the beginning of this, the first person I called for any advice was you. And I was like, 'Hey, I don't want to bother you, but this is my idea and what I want to do. What would you say? How would I start?'"

Kim told Hailey how she had followed Rhode from the start and is proud of her, as Hailey continued to say, "I remember you giving me so many good pieces of advice in terms of like, 'Here's how I did it. This is a way that worked for me. I think you have to find the way that will be the best thing for you as Hailey'… And that was precious advice for me."

Kim also recalled when she was working on her skincare line and thought she finally made it when Hailey complimented her glowing skin.

The two long-time friends are part of a mutually appreciative society.

Later, Hailey decided there's been enough talk, so they needed to kick things up a notch by playing a drinking game called "Truth or Shot," where the person had to answer a question truthfully or drink a shot. Predictably, Kendall Jenner's 818 Tequila.

It starts with Hailey asking Kim what she thinks is better, make-up sex or angry sex, and Kim prefers the former. Kim asks Hailey what's her biggest turn-on, and she answers it's kissing.

Things take a spicier turn when Hailey asks Kim who was her worst date and takes a fifth, so she takes a shot. Finally, when the supermodel asks the mom-of-four who her celebrity crush is, Kim plays coy because she wants it "to come true." When Hailey asks her to come clean and take her chance, the business mogul declines, saying she's more into privacy these days and so takes another shot.

Hailey won the game, and as per the rules, Kim had to post a picture of Hailey on her IG stories, so she did.

Hailey also asked KimK the age-old question, how she manages to do it all with multiple businesses and four beautiful kids?

Kim says that while every aspect of her life is micromanaged, she has learned to deal with the chaos of being a parent. She gave an example of how, even before she met Hailey, one of her kids fell and had to be taken to the dentist to ensure no teeth were chipped. But that's part of her life; she says, "Every parent that acts like they have their s--t together is acting, so winging it is my way of coping. It's just the reality. I'm winging everything."

Later, Kim also talks about how her morning workouts keep her calm and stress-free, ready to take on the day.
