Kristen Stewart has reportedly dropped out of her role in 'Cali'.
The 22-year-old actress - who recently cheated on boyfriend Robert Pattinson with her married 'Snow White and the Huntsman' director Rupert Sanders - is said to have pulled out of starring in the gritty action thriller, with Amber Heard tipped to take her place in the motion picture.
Sources revealed to Gossip Cop that the blonde beauty has been asked to join the cast of 'Cali' - which will be directed by Nick Cassavetes - but it's not confirmed whether she has agreed to take on the role.
Kristen is also due to co-produce the movie, which tells the story of two lovers - Mya (Kristen) and Chris (Alex Pettyfer) - who ride off into the sunset with a bundle of cash after selling a fake snuff film, but they are forced to return to Los Angeles years later to save Mya's younger sister from villains.
It is unknown whether Kristen will continue on the film in a producing capacity, and the brunette beauty is also said to have pulled out of the London premiere of her forthcoming movie 'On the Road'.
The 'Twilight' actress is said to be "too ashamed" to be seen in public on the red carpet later this month in the wake of cheating on Robert, who is due to star alongside her in the last instalment of the 'Twilight Saga' franchise later this year.
A source told RadarOnline: "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."
