Robert Pattinson has been on the down low since finding out his girlfriend and Twilight co-star Kristen Stewart cheated on him with director Rupert Sanders, but a movie distributor has confirmed when the actor will be making his first public appearance.
Pattinson will make his first public appearance Aug. 13 at the New York premiere of his new film, Cosmopolis, the film's distributor, eONE Films said, according to E! News.
Meanwhile, security staff have allegedly been told to keep Stewart away from the red carpet and after party for the 'Cosmopolis' screening, because she may use it as an excuse to speak with her ex-boyfriend in person.
A source told website RadarOnline: ''Despite the fact Robert and Kristen have been communicating by cell phone, she will not be at the 'Cosmopolis' New York premiere.
The insider continued: ''The decision was made because Robert just doesn't want to see her. There were fears that she could use it as a chance to talk to him in person and that sort of drama is not wanted at the premiere.
''There's also the fact that if she did attend, it would distract from the film premiere itself and the movie bosses are not interested in that sort of publicity. It's going to be Robert's first public appearance since the scandal broke - and they really want to make it less of a media circus than it already will be.''
The couple has not yet spoken in person since the affair was played out in photos on UsWeekly.
Pattinson stars as a 28-year-old billionaire asset manager who is riding across Manhattan in a stretch limo in order to get a haircut. His day devolves into an odyssey with a cast of characters that start to tear his world apart.
