Robert Pattinson is nursing his broken heart at Reese Witherspoon's Ojai. Calif. estate – but his self-imposed exile can't last forever.

Pattinson, 26, stars in the new movie Cosmopolis, due out in theaters Aug. 17. And despite reports that the Twilight star – whose girlfriend Kristen Stewart cheated on him – has cancelled promotional appearances for the movie, he will show up to support the film in a few short weeks.

"Cosmopolis is a film that Robert is very proud of and looks forward to supporting," his rep said in a statement Wednesday. "No confirmed engagements have been canceled. Any reports to the contrary are inaccurate."

So the fiercely private Pattinson will have to face the media and fan frenzy during the Cosmopolis premiere in New York City on Aug. 13 and speak to reporters at a press event the following day.

Cosmopolis is directed by David Cronenberg and also stars Juliette Binoche.
