Beyonce Video: sexy or not?

Okay, so I just watched "Single Ladies (Put a Ring on It) by Beyonce---the video. What caught my eye was (again I swear I am heterosexual) the sexy picture of her by Scott Gries, Getty Images North America on getback.com. She looked pretty smexy, so I thought I would check out the video. Something about the video was off. I'm not sure if it was the costumes, the dance or what. The ladies looked short and chunky (in a sexy way). The dance seemed a bit awkward and not sure if it was sexy or not, frankly. Please watch it and give me your opinion. Thanks!
