Need a fierce fix? Project Runway
winner Christian Siriano
, who was famously spoofed on Saturday Night Live
, 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." In addition to the outfits he designed for his model pals, the Runway
winner also whipped up a look for Becki Newton
(Amanda) -- who happens to be a huge Christian fan.
So, who was the fiercest cast member of them all? "Ooooh, they're as fierce and ferocious as they can be," raves Siriano. "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!" --Rennie Dyball
