One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
All eyes were on Leighton Meester at the Sunday night premiere of her new flick The Roommate.
While everyone else wore short cocktail dresses, Leighton chose a leather and chiffon Michael Kors gown.
There's no denying she looks fabulous, but we're kinda getting tired of seeing different parts of her torso.
But whatevs. If you've got it, flaunt it.
