Project Runway winner Christian Siriano is back on TV, playing himself in on ABC’s Ugly Betty in an episode airing May 1.

The plot: Mode magazine is trying to convince Christian to work with them for a fashion spread instead of their competitors. So the designer shows up for a meeting with an entourage of models wearing his designs and Runway judge Nina Garcia, who also plays herself on the episode.

“Filming Ugly Betty was amazing,” Siriano, 22, tells PEOPLE. “The cast was the most fun, lively and supportive ever.”

This sounds like the best Ugly Betty episode yet!!
