Gossip Girl star Leighton Meester shinned in mirrored short dress with long sleeves by Balmain on the red carpet of the 2011 MTV Movie Awards held at the Gibson Amphitheatre in Los Angeles, California on Sunday (June 5)- more pictures below.

The 25 year-old actress and Twilight star Kristen Stewart wore completely different Balmain creations, but they stood up as edgy, young and fun on the red carpet. What’s your favorite Balmain dress: Kristen’s or Leighton’s? I’d pick Kristen’s because it’s red and strapless (photos here).

Leighton was up for the Best Villain award (“The Roommate”) but lost to Tom Felton (“Harry Potter And The Deathly Hallows – Part 1”). She finally took over the stage with her “Monte Carlo” co-stars, Selena Gomez and Katie Cassidy, and they introduced a performance by rapper Lupe Fiasco.
