(Cover) - EN Movies - Kristen Stewart is currently penning the script for her new project alongside her mother, according to a source.

The American actress, who is best known for her portrayal of Bella Swan in the popular vampire franchise Twilight, is reportedly co-writing the script for her next project since wrapping the Twilight saga more than two months ago.

The 21-year-old star is currently in Los Angeles where she is busy working on her upcoming movie, K-11 with her mom, Jules Mann-Stewart.

"Kristen is at home right now in LA working with her mom, Jules, on their movie, K-11," an insider told HollywoodLife.com. "I think she's going to be a producer and a scriptwriter on the film."

Kristen has been working on K-11 for more than two years. The movie follows the story of an autistic transgender named Butterfly who meets a fellow transgender named Mousey in jail.

Nikki Reed, who was originally set to star in the drama, revealed earlier this year that she was no longer attached to the script.

K-11 will be directed by Jules, and is scheduled to begin shooting next month. (C) Cover Media
