It's the "Attack of the Show" hostess, Olivia Munn (aka every fan boy's wet dream). Since 2006, Munn has been one of the most popular faces of the G4 cable network, hosting a number of shows, most prominently "Attack of the Show", which is devoted to the world of video games and the video game lifestyle (with a liberal dash of other media stuff, including comic books).

Munn has also been a successful model for Nike, Pepsi and Neutrogena and has appeared in magazines such as Men's Health, Vanity Fair, Playboy and Maxim. Additionally, the lovely Olivia has acted in minor horror, teen & comedy films, but is set to appear in the big budget sequel, Iron Man 2 in 2010.
She really does have that "girl next door" quality that geeks & nerds respond to and then effectively channels an engaging and bubbly form of sexuality, all the while dressed up as Princess Leia, Wonder Woman or other female genre icons. Now that's what I'm talking about!
