Waterhouse, who has been dating Bradley Cooper since 2013, will play Marlene, a member of one of the film’s sci-fi world factions called Dauntless. She joins a star-studded cast including Shailene Woodley, Theo James and Kate Winslet, who are all returning to the follow-up to the hit Divergent, which is based on Veronica Roth’s young-adult book series.
This will be the British model’s fourth film appearance. Waterhouse, 22, also had a previous television role on the TV series Material Girl in 2010.
Insurgent is set to hit theaters on March 20, 2015.
