Twilight star doesn't feel strong enough to face the public

Kristen Stewart has cancelled a red carpet appearance in London following the exposure of her affair with film director Rupert Sanders.

The 22-year-old actress, who betrayed Twilight co-star boyfriend Robert Pattinson, was due to attend a screening of new movie On The Road in London next week but has now pulled out.

Kristen won’t be doing the red carpet for On The Road,’ reveals a source.

She’s too ashamed to show her face in public right now. After everything that has been said, and in the light of revelations that she cheated on Robert, she’s running scared at the moment.’

It’s thought that K-Stew was also worried about standing next to co-star Tom Sturridge because he’s a good pal to R-Pattz, 26.

He’s very close to Rob and Kristen thinks it would be awkward for her to promote the movie on the red carpet alongside him,’ the source tells Radar Online.

Whilst Kristen is still struggling with the aftermath of the affair, it’s believed that Liberty Ross, the wife of Snow White And The Huntsman director Rupert, wants to save their marriage and doesn’t plan on divorcing her cheating hubby.
