Hah, this thread made me hit Google for celebrities that game; and apparently a lot of them like WoW - including Janina Gavankar, who does seem like one of the actual gaming celebrities if you look at her twitter and various interviews.
She mentioned in the interview with MOG Nation
that she's looking to play more video game characters AND she tweeted:
"Janina Gavankar @Janina 1 december
I WON THE LEGO STAR WARS DEATH STAR II ON EBAYYYYYY"
So obviously she's a Star Wars fan - what are you waiting for Bioware?
