Gabrielle Union will guest star on Ugly Betty as Wilhelmina's younger sister, Dominique. Dominique is said to have a very wild side with a skeleton or two in her closet.

My guess is she's Wilhelmina's daughter. What? That could happen. Or she's a porn star, which would be hilarious.

Gabrielle's character was supposed to be recurring, but because of the writer's strike, she's only been hired on for one episode.
