Kristen Stewart is reportedly refusing to talk about Robert Pattinson.

The 22-year-old star, who skipped Thursday night's London premiere of her new movie 鈥淥n The Road,鈥 will remain in hiding until next month's Toronto International Film Festival.

She will then go into full-promotional mode to sell her latest movie, but doesn't plan on doing an interview to address her cheating scandal any time soon.

A source close to the actress revealed to website RadarOnline: "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.鈥

Unlike Rob, who faced the music and threw himself into promoting his new movie 鈥淐osmopolis,鈥 Kristen isn't comfortable with facing a barrage of questions about the cheating scandal.

Friend have apparently advised the 鈥淭wilight鈥 star to do as her ex-boyfriend has done to better her public image but Kristen is worried her fans are still angry.

The insider continued: "Her pals have urged her to follow Robert's lead and do some interviews for 鈥極n The Road鈥 -- just to get it over and done with. The sooner she faces the music, the quicker it will all end and the media glare will fall on someone else.

"However, Kristen is scared. The backlash from her 'Twilight' fans has upset her - she's lost and doesn't know what to do.鈥

Kristen apologised soon after news broke of her affair with 鈥淪now White and the Huntsman鈥 director Rupert Sanders.

She said: "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardised the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."
