Kerry Washington made an appearance at New York Fashion Week on Friday.

Jumping from one Emmy nominated show to another, she acted as guest judge for the Project Runway season finale.

She joins judges Heidi Klum, Zac Posen and Nina Garcia for her third time on the show.

Though she admitted to being nervous for having to judge people, the Scandal star knows her stuff. "I've had to learn about fashion because as an actor, it's such a huge part of the marketing," she told Abc News. “I do my research. I stay informed. I communicate with the designers”, she added.

Washington also communicates with the designers on the Scandal set. In an interview with Access Hollywood, she gushed that one reason she loves playing political PR superhero Olivia Pope is because she gets to use her fashion wisdom to help decide what Olivia would wear.

“I know when I put something on whether it’s Olivia or not. And it helps me to get in character.”

Not only was the star there to judge, but she also made a trek down the runway during the show. She wore a gorgeous floral Stella McCartney dress and red patent pointed toe pumps.

Heidi Klum tweeted her love for the star after filming.

Project Runway airs Thursdays at 9 on Lifetime.
