ABC's "Ugly Betty" may have been given the pink slip -- news of the show's cancellation broke last week -- but there's still one very stylish guest star to ensure that the show goes out with a bang.

Designer Brian Reyes is set to appear as himself on the fashion magazine-centric series this Wednesday in a fashion week story line. The scene takes place in a restaurant where a show is about to take place, according to WWD.

"Onion rings are involved," Reyes told the paper. While food and fashion, um, aren't exactly known for going hand in hand, the cameo seems to be the product of a long red carpet relationship.

The Oscar de la Renta alum has previously dressed Betty star America Ferrara, including for the 2007 Golden Globes and for "The Sisterhood of the Traveling Pants 2" premiere, where the actress wore a bright blue strapless number

But don't expect Reyes to jump ship for Hollywood anytime soon. With a real-life fashion week coming up and runway collaborations with British shoe maven Georgina Goodman and Ukrainian artist Oksana Mas, the designer is plenty busy.

As for a future in Tinseltown? The New York-based designer joked with WWD on his acting skills, "I'm definitely not quitting my day job."

Despite his ladylike designs, Reyes' history of collaborations isn't so prim and proper (well, not prim, at least). He last teamed up with condom brand Proper Attire.
