Kim Kardashian and Kylie Jenner's biggest confessions from their latest viral YouTube video

Kim Kardashian joined her younger sister, Kylie Jenner, for her latest YouTube video, which involved Kylie doing Kim's makeup while they answered fan questions that had been submitted via Twitter.

Throughout the 11-minute clip, called "Get Ready With Us: Kim and Kylie," the sister duo divulged some major tea about their lives, including Kylie's plans to have more children, the unexpected person who came up with the name of Kim's first child, North West, and the sports record that Kylie set while she was in school.

If you don't have the patience to watch the Kardashian-Jenners' latest makeup tutorial, we've rounded up Kim and Kylie's biggest confessions from their new YouTube video for you below:

Kylie wants to have four kids — but she's not sure when she'll have them: After answering a fan's question about how she handles having four children, Kim turned the question around on Kylie and asked if she thinks she'll grow her brood beyond her one daughter, Stormi Webster.

"I see myself for sure having four kids, I just don't know when," she said. "I don't have a timeline to this, and I don't know if I'm gonna have four kids tomorrow or have four kids in, like seven years."

North West's name originated from a sarcastic suggestion made by Jay Leno: The Kardashians have become known for their unorthodox baby names, but that can all be traced back to Kim and Kanye's decision to name their first child North West. While she was getting her makeup done by Kylie, Kim revealed that she first got the idea from a joke that former late-night host Jay Leno made when she was on his show while pregnant.

"North, took me like a week to name her. Not a week, like four or five days. I actually got it from Jay Leno, who made that as a joke, and I was like, 'No way I would never name my daughter that.' Like, I said that on his show," she laughed. "Everyone was coming up to me like, 'It's such a cool name, you should really think about it,' and then Pharrell had all these meanings [behind the name.]"

Kylie is "really good at sports" and actually set an athletic record at her old school: The Kylie Cosmetics mogul revealed that she was on a boys' football team back in the day, and her proficiency at sports led her to set a school record in track and field.

"I think that people don't know that I'm really good at sports. I was on the boys' football team — only flag, until they started tackling everybody and then I was like, 'I'm outta here,'" she revealed. "I love track. I set the record for my school in the high jump."

Kylie likes to dance — just don't expect to ever see her doing it in public: The youngest of the Kardashian-Jenner clan loves to sing ("Rise and Shine," anyone?) and dance with her friends at home and private parties, but she isn't totally into letting loose like that that in public.

"Kylie always used to love to dance like Shakira, and I was blown away that she can move her stomach like Shakira did in that song," Kim said of Kylie when she was little.

"I just do not like to dance in public," Kylie added.

Kylie's first car came from her mom, Kris Jenner — and Kim had already crashed it: While Kim revealed that she no longer has her iconic black Bentley, Kylie added that she also no longer has her first car, which once belonged to their mom.

"I'm so mad at myself for giving away my first car," Kylie lamented while doing Kim's makeup. "Mom's first G-Wagon."

That's when Kim recalled her own memories with the vehicle: "I remember I crashed that car — bad."
