The couple, who were rocked by pictures of the 22-year-old actress in an intimate embrace with director Rupert Sanders, are scheduled to join Twilight co-star Taylor Lautner for an interview on MTV to discuss the final film in the series, The Twilight Saga: Breaking Dawn - Part 2.
Following the US television appearance, a "lengthy interview" will take place on MTV.com, HollywoodLife says.
Despite a turbulent few months, an insider told the website that the couple are back together and spending as much time together as possible.

"They are not living with each other, but they are spending plenty of time with each other and they do sleep over often. Rob usually sleeps over at Kristen's new home in Los Feliz, rather than the other way around."
Pattinson and Stewart are expected to appear on the red carpet together along with the rest of the Twilight cast for the film's November premiere.
