Kristen Stewart mtv movie awards

Kristen Stewart is having a killer weekend!

Her latest flick Snow White and the Huntsman dominated at the box office this weekend, and the Twilight star won "Best Kiss" tonight with beau Robert Pattinson!

The raven haired beauty looked simply stunning in a funky silver dress by Guishem with bold yellow and purple patterns, paired with sexy Christian Louboutin stilettos.

The fans still love her and Robert Pattinson together, even though the English hottie was absent. Check out Kristen's solo acceptance for Best Kiss ...
