We spotted "Twilight" stars and real-life couple Robert Pattinson and Kristen Stewart arriving at their hotel in San Diego ahead of Comic-Con today.

Robert signed autographs and posed for fans, while Kristen walked right into the hotel looking a bit more well endowed than usual.

Twenty-eight cast members are scheduled to take the stage to discuss the conclusion to the "Twilight" film series, "The Twilight Saga: Breaking Dawn - Part 2," which hits theaters in November.

On Tuesday, a 53-year-old woman died after she was hit by a car while crossing a road to take her place in a line for a "Twilight" panel discussion at Comic-Con on Thursday.
