Buzz has it that Twilight actress Kristen Stewart has pulled out of the London premiere of her film On the Road because she is too embarrassed to appear in public in the wake of her cheating scandal.

Earlier the 22-year-old actress was originally planning to walk the red carpet for the adaptation of Jack Kerouac's classic novel on August 16 with co-star Tom Sturridge, a close friend of Robert Pattinson but she has had second thoughts.

“Kristen won't be doing the red carpet for On the Road; she's too ashamed to show her face in public right now. After everything that has been said, and in light of the revelations that she cheated on Robert with director Rupert Sanders, she's running scared at the moment,” said a source.

The insider continued: "There's also the dilemma of standing next to her co-star in the movie, Tom Sturridge. 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. Kristen is very proud of her work for On the Road, she grew up reading Kerouac novels and this is a production she always wanted to star in."

They added: "If she appears at the London premiere, it will detract people from the movie itself and Kristen doesn't want that at all.

Awww…we’re really worried about you Kristen!
