Pattinson and Stewart have not met since the actress apologised for her affair with married director Rupert Sanders last month.
Stewart skipped the red carpet of her last film 'On The Road' in the wake of the scandal but Pattinson has since done TV appearances to promote 'Cosmopolis'.
The actor has been avoiding questions related to his private life but it is said that he will appear for the LA opening of 'Breaking Dawn II' in November, the Sun reported.
"He's told movie bosses he'll walk the red carpet to save her from embarrassment and any female fans booing her. He is being professional and taking the higher moral ground," the tabloid reported quoting sources.
