Kendall Jenner 'Very Mad' at Caitlyn for Announcing Her Appearance at Victoria's Secret Show

The reality star expresses her concern in new 'KUWTK' preview.

Kendall Jenner ruled the runway at the Victoria Secret Fashion Show, but she was nevertheless fearful that one family member would steal her spotlight.

In this peek at Sunday night's episode of Keeping Up With the Kardashians, Kendall and Caitlyn Jenner go head to head after ET broke the news that Caitlyn would be attending the annual event that took place back in November.

"Hi, Dad. I'm very mad at you about some things," the 20-year-old reality star tells Caitlyn on the phone while getting ready for Kris Jenner’s Great Gatsby-themed birthday party. "Did you have your publicist announce that you were going? Because I don't know how everyone knows, and now it's a huge story, and I'm actually pissed at you."

Although Caitlyn’s responses can't be heard in the clip, Kendall gives us a pretty good idea that Caitlyn isn't saying what her daughter wants to hear.

"OK, well then you knew that was going to happen, and that's so annoying," Kendall says before snapping, "OK, well then I don't want you to go!"

"You're going to take the biggest night of my life and take it away from me?! Thank you," she continues. "No! You can't [come]! You can come to the f**king afterparty, you can't come [to the fashion show]."
