According to OK! magazine, a little rivalry is developing between Pattinson's girlfriend Kristen Stewart and his Cosmopolis co-star Sarah Gadon. They wrote:
"Robert Pattinson's new sexy leading lady is getting sweet revenge on Kristen Stewart. Actress Sarah Gadon first tried out for the coveted leading part in Snow White and the Huntsman — but Kristen snagged her dream role! So what did Sarah do? She landed a part opposite of Kristen's boyfriend Rob, playing his wife in the film Cosmopolis, which started filming in Toronto last week.
"While Kristen got the big starring gig as Snow White, Sarah gets to spend all day with Rob for two months straight — and likely share some on screen smooches with the Twilight hunk while they film Cosmopolis together."
