Kristen sad about spplit with Rob.

Kristen Stewart has been spotted out and about in LA this week, the US actress recently split with long-term boyfriend Robert Pattinson and has been in hiding since.

Photos of the star sporting a backward baseball cap and a midriff-baring T-shirt top were published and she had a frown on her face.

USA Today notes that in the photos, KStew "was not smiling and did not appear happy about being photographed."

No wonder - Stewart was busted by the paparazzi kissing Rupert Sanders and once Rob found out, he dumped her.

Don't expect any revelation coming forward from Kristen, the brunette beauty is reportedly refusing to even talk about her ex-boyfriend RPatz.

The 22-year-old star, who skipped last week's London premiere of new movie 'On The Road', will remain in hiding until next month's Toronto 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.

"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.

Friend have apparently advised the 'Twilight' 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 'On The Road' - 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.

Kristen apologized soon after news broke of her affair with 'Snow White and the Huntsman' 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."
