Christian Siriano on Ugly Betty — FIRST LOOK!

Project Runway winner Christian Siriano poses with Becki Newton while shooting an episode for Ugly Betty, which airs on Thursday, May 1.

“Filming Ugly Betty was amazing,” the 22-year-old designer says. “The cast was the most fun, lively and supportive ever. They’re as fierce and ferocious as they can be. Vanessa Williams is the queen of fierceness and Becki Newton is the princess … I’m inviting them all to my Spring 2008-09 collection — it’ll be a great front row!”

Project Runway judge Nina Garcia will also be playing herself on the episode.
