Watch: Has Kier Lost Her Mind on "House of DVF"?

She's had major meltdowns and various freak-outs on House of DVF, but has Kier Mellour officially lost it?

In this exclusive peek at Sunday's season finale, the remaining three Brand Ambassador candidates are working on the dress rehearsal for Diane von Furstenberg's big show. As everyone waits for the models to come out one at a time, Kier suddenly appears on the runway, causing the designer's jaw to drop!

"So here I am, watching the rehearsal," Diane reveals to the camera. "All of a sudden I see Kier walk out on the runway! I thought, 'She has gone crazy!'"

E!

The rest of Diane's team is just as shocked by what's going on!

"Kier came out following the models," Stefani Greenfield remarks. "She has lost her mind!"
