Marc slapping Willie's mannequin

I've be re-watching season 3. I just saw "Crimes of Fashion" in which we discover who really pushed Christina down the stairs. In the episode there are some scenes when Marc admits to arguing with Willie mannequin to vent his hostility. Even though I had seen the episode 3 times before (I'm on my fourth viewing of the series) I hadn't paid close attention to the mannequin. This time I noticed a slight movement of the frozen dummy. I paused the dvd and looked closely... it's really Vanessa Williams! She's got scary makeup on to make her look artificial, but it's her. I paused the dvd and look at the next scene, and yes, it's really her.

The first 3 times I saw the episode I thought it was a dummy made up to look like Willie, the 4th time I wasn't fooled. Vanessa does a great job looking frozen in place.
