ET has an inside look into the DVD extras found on 'The Twilight Saga: Eclipse.'
The extras include a special interview with Kristen Stewart who opens up about working with her rumored boyfriend Robert Pattinson on the set of the third movie.

Kristen, who plays Bella Swan, comments on her onscreen chemistry with Rob, who plays her love interest Edward Cullen, saying, "We have established dynamics that no one can mess with."
