Stewart wants to avoid break-up-related queries

Los Angeles, Aug 19 (IANS) Actress Kristen Stewart is not comfortable talking about her much-talked about fling with director Rupert Sanders.

Stewart had an affair with her "Snow White And The Huntsman" director Sanders while she was in a relationship with actor Robert Pattinson.

The 22-year-old, who has been keeping a low profile of late, will have to face the media to promote her forthcoming movie "On The Road" at the Toronto International Film Festival, starting Sep 6.

"Unlike Rob, who faced the music and threw himself into promoting his new movie 'Cosmopolis', Kristen isn't comfortable with facing a barrage of questions about the cheating scandal," Perezhilton.com quoted a source as saying.

"Kristen has been hiding ever since the story of her affair with Rupert broke and she doesn't plan on breaking that habit just yet," the source added.

Stewart plays Marylou in the book-to-movie adaptation of Jack Kerouac's classic novel of the same name.
