It takes a lot for Kendall Jenner to lose her cool, but something Caitlyn Jenner did really set her off.
In a sneak peek clip from this coming Sunday's episode of "Keeping Up with the Kardashians," we see the model confront Cait about trying to steal her thunder before walking in the Victoria's Secret Fashion Show.
"I'm very mad at you about something," Kendall says during the tense phone call. "Did you have your publicist announce that you were going [to the runway show]? I don't know how everyone knows and now it's a huge story and I'm actually pissed at you."
The 20-year-old stunner sounds ticked that Cait brought the spotlight on herself before the show.
"You're gonna take the biggest night of my life and take it away from me, thank you!" Kendall then exclaims. "You can come to the f--king after party. No you can't come [to the show]."
In a confessional, Kendall explains that she's actually had to work "even harder" than most models because of her famous family, adding that she's scared of the "media frenzy" that will happen if Caitlyn were to show up.
Of course, we all know that Cait and Kris Jenner attended the fashion show back in November, even posing together for photos at the event. The two definitely made headlines, but in the end, everyone was still talking about Kendall's big debut.
