It was an exciting day for Twilight fans, as the cast of Breaking Dawn made an appearance at Comic-Con in San Diego - and RadarOnline.com has the
autographs and pose for photos at the annual convention.
While her costars got a little more dressed-up for the promotional appearance, Kristen wore a totally sheer Market White Patti Tee (which revealed her black bra!) with dark jeans.
Twilight fans camped out over night for a chance to see their favorite stars and were thrilled to have Nikki Reed and Ashley Greene come out and sign autographs before the panel started.
The Twilight Saga: Breaking Dawn - Part 1 is set to hit theaters on November 18.
