Kristen Stewart might have issued a very public apology after news broke that she cheated on boyfriend Robert Pattinson with married director Rupert Sanders, but the young actress has since been mum and has even dropped out of an upcoming film.

Both Variety and GossipCop confirmed that Stewart has dropped out of a leading role in "Cali," a film directed by Nick Cassavetes and written by Michael Diliberti.

Stewart was set to star in the movie about San Fernando Valley lovers Mya (Stewart) and Chris (Alex Pettyfer), who sell a fake snuff film and escape with the cash only to "return from the dead" to save the younger sister Mya left behind.

GossipCop reports that Amber Heard has been asked to join the "Cali" cast, but it remains unclear whether Heard will take over Stewart's part.

According to the film's IMDb profile, Stewart is also credited as an executive producer. There is no word whether she will remain a part of the film in this capacity.

"Hopefully after all of this we can go and we can do it in the summer, like lock ourselves away for a few weeks in the Valley [in L.A.] in a little production office and get together really weird, freaky actor people," Stewart previously told MTV while promoting "Snow White and the Huntsman," the film that brought her and Sanders together. "It's filled with like the coolest characters."

Stewart has kept quite a low profile since she issued an apology to Pattinson via People magazine in July.

She was reportedly spotted by several witnesses at Gold's Gym in Venice, Calif., over the weekend, according to E! News. But others claim that rumors of any gym sightings are false and that Stewart has not been therefor quite some time.

Meanwhile, Pattinson has been camping out at friend and "Water for Elephants" co-star Reese Witherspoon's Ojai, Calif., vacation home. He is scheduled to appear in his first post-scandal interviews with "The Daily Show" (Monday, Aug. 13) and "Good Morning America" (Wednesday, Aug. 15).

On Tuesday, Sanders was photographed with his model wife, Liberty Ross, outside a deli in Los Angeles. TMZ reports that Ross, who has already seen a divorce lawyer, hopes to work things out with her cheating husband.
