It's good to be Kendall Jenner right about now.

She's fashion's new "it" girl scored her first solo editorial for Vogue’s December issue and just landed a major endorsement deal with Estee Lauder as the latest face of the beauty brand.

And in the midst of all of that, she decided to sit down with "Nightline" and set the record straight on a few rumors that have been swirling around her for quite some time.

First up, is she really dating Justin Bieber? The two have been spending quite a bit of time together, and in the wake of the latest Jelena break-up, some are assuming these two are more than friends.

"He's a longtime friend of our family," she said. "Everybody loves to assume things, but no."

Well that settles that...for now.

Kendall also set the record straight on whether big sister Kim, who is busy breaking the Internet, was actually banned from her fashion shows, which is true...sort of.

“It was more of a mutual understanding,” she said. “I remember getting a phone call from Kim… ‘I just wanted to let you know, I just got an invite to the Marc [Jacobs] show. I don’t think it’s a good idea that I go. Do you agree?’ And I was like, ‘I completely agree’ ... She obviously is who she is, and it would’ve almost taken the attention away from me.”

Some were shocked at her appearance at the Marc Jacobs show, which had walking the runway in a sheer top.

“Who’s going to argue with Marc Jacobs when he’s putting you in an outfit, you know what I mean?” said Kendall, who dropped her last name from her modeling cards. “It was an amazing moment. And I do not regret it.”

But there was one story in particular this year that wasn't as easy for Kendall to brush off, and that was the separation of her parents Bruce and Kris Jenner.

“It sucked, but it’s not -- I try to think of it as it’s not the worst thing that could have happened,” she said. “I still am so close with both my dad and my mom. Nothing has really changed, except for the fact that now my dad lives on a beach, which is awesome. That’s not that bad... everybody’s happy.”
