'Project Runway All Stars' Episode 2 preview: The designers get personal [Exclusive video]

Wendy Pepper, the prickly "Project Runway" alum fans loved to hate during her season one stint on the show, has made a friend on "Project Runway All Stars," and no one seems more surprised than she is.

I have found one of the most incredible people I think I've ever met," Pepper says of her new BFF, the single-monikered Suede, in an exclusive preview of Thursday's new episode.

And while Pepper and Suede are bonding over hair dye and Pepper's further surprise at Suede's revelation that he has experience with ladyparts, the season's other one-name designer, Casanova, is embracing the week's disco-themed challenge.

"You know what I like about this challenge?" Casanova asks. "Nightlife … slutty … Casanova."

"Project Runway All Stars" airs Thursdays at 9 PM on Lifetime.
