Robert Pattinson has agreed to appear with his ex Kristen Stewart at the premieres of their new Twilight film despite her affair, according to reports.
But The Sun said that the actor, 26, had insisted he won't discuss his former girlfriend, 22, who has also agreed to be there, in any interviews.
A source was quoted as saying: "It's a purely business decision. He's keen to make sure fans and Hollywood see he can be professional when it comes to Kristen."
Kristen admitted to an affair with her Snow White And The Huntsman director Rupert Sanders in July.
British actor Robert appeared with Twilight co-stars, but not Kristen, when he presented the final trailer for the last film in the series, Twilight Breaking Dawn: Part 2, at the MTV Video Music Awards.
