Kristen Stewart: 'Rileys' Red Carpet!

Kristen Stewart walks the carpet at the premiere of her film Welcome to the Rileys at the 2010 Los Angeles Film Festival on Friday (June 25).

The 20-year-old actress must have been a little nervous during the Q+A because she was biting her nails while sitting in her chair! Also attending the premiere were Kristen‘s costars James Gandolfini and Melissa Leo.

Welcome to the Rileys won’t be released until October, but you can see Kristen in The Twilight Saga: Eclipse, which comes out on Wednesday!

FYI: Kristen is wearing Preen‘s Amour dress and Jimmy Choo shoes.
