Kristen Stewart - MTV Movie Awards 2009

Kristen Stewart dresses down her Yigal Azrouël embroidered taffeta dress with a pair of Converse sneakers at the 2009 MTV Movie Awards held at the Gibson Amphitheatre on Sunday evening (May 31) in Universal City, Calif.

The 19-year-old Twilight actress and costar Robert Pattinson won a Golden Popcorn statue for “Best Kiss”. The twosome beat out Wanted‘s Angelina Jolie and James McAvoy, Slumdog Millionaire‘s Dev Patel and Freida Pinto, Milk‘s Sean Penn and James Franco, I Love You Man‘s Paul Rudd and Thomas Lennon and High School Musical 3‘s Zac Efron and Vanessa Hudgens.

UPDATE 1: Kristen is wearing sneakers because she twisted her ankle. She was supposed to wear pumps!

UPDATE 2: Kristen also picked up “Best Female Performance” for Twilight. During her acceptance speech, she dropped the Golden Popcorn statue and awkwardly tried to catch it. Hilarious! Watch the clip below…
