Pattinson and Stewart will promote final 'Twilight' film together

Robert Pattinson and Kristen Stewart will reunite at the 'Twilight Saga: Breaking Dawn Part II' premiere.

The 26-year-old actor, who was left heartbroken in July after his girlfriend and co-star was caught cheating with married 'Snow White and the Huntsman' director Rupert Sanders, has agreed to be "professional" and attend the Los Angeles screening with the brunette beauty in November because he is worried about how fans will react when they see the actress.
