In honor of Christian Siriano's fierce guest-starring role on tonight's Ugly Betty, take a look back at other notable stars who've made pit stops at Mode. Let's hope the Project Runway sensation follows the success of these previous guests.

Gene Simmons: Poor little Amanda (Becki Newton) had some major daddy issues. Wouldn't you if you narrowed down your mother's list of many suitors to none other the legendary KISS rocker Their first meeting brought tears (of laughter) to our eyes.

Gabrielle Union: As Renee Slater (Wilhelmina's little sis), Union managed to charm the pants off Daniel Meade while simultaneously blackmailing her sister and keeping her own murky past a secret.

James Van der Beek: Dawson has had success guesting on hit shows lately. Before How I Met Your Mother, he was the bigoted head of a major clothing company who pushed Daniel to set aside his sibling rivalry and defend his sister's honor.

John Cho: Where would Henry be without his wannabe-gansta office bud Kenny Or better yet, where would the viewers be without his one-liners This guy is what you would call a legend. Well, at least in his own mind.

Victoria Beckham: This former Spice Girl decided to give American TV another whirl when she guest starred as herself as one of Willie's celebrity bridesmaids during the ginormous Bradford wedding affair.

Kristin Chenoweth: Having been a star on Broadway, it's no surprise that Chenoweth brought tons of personality to a role as small as a chatty orthodontist's assistant. We can't help but think this helped her score the gig on Pushing Daisies.

Gina Gershon: Even in the pilot Ugly Betty scored a major guest star. Gina Gershon's Fabia has since returned twice to stir things up at Mode. The character is so frigid, she was able to hold her own against the queen of mean, Wilhelmina Slater.

Lucy Liu: After seeing her chop off some poor dude's head in Kill Bill, it's odd to watch Lucy Liu do anything but kick ass. But her turn as a former nerd turned heartbreaker has us hoping to see more of the Meade family attorney in the future.

Eliza Dushku: The Buffy vet channeled her inner Britney, playing a pop star/recovering addict tapped to be on the cover of one of Mode's biggest issues. Her appearance made us remember how great she is in the right role. Bring on Dollhouse!

Salma Hayek: Only someone as hot as Betty producer Salma could get Daniel Meade to give up his bachelorhood and put a big ol' rock on her finger in less than a season. Too bad it was all for a story in her magazine.
