Cat explodes on Hanna Beth and Alli during the season two finale of House of DVF.
In this exclusive clip from this Sunday's episode, Cat gets upset after she thinks her musical act can't perform at the lunch they're planning for Diane von Fürstenberg.
Cat tries to get Tori Kelly to perform at the lunch, but it doesn't seem like it's going to happen. So Alli decides to call Justine Skye who she thinks would be a great choice if Tori can't make it, and Cat is worried that Hanna Beth and Alli are going to turn on her.
"If we're gonna go there, you've thrown people under the bus before in front of Diane and Jessica," Alli says to Cat.
Hanna Beth reminds Cat that she didn't think Alli could make it this long in the competition.
"You said that you were born into this and she wasn't," Hanna Beth says.
"Stop with the f—king born into it," Cat tells Hanna Beth.
Take a look at the clip above to see the explosive argument between Cat, Hanna Beth and Alli!
