Kristen Stewart will star in a Snow White and the Huntsman sequel - but director Rupert Sanders will not be returning.

The Twilight Saga actress has signed on to reprise her role as the fairy tale princess, but Rupert - who helmed the first movie - will not be taking part in the new project following his affair with Kristen. The filmmaker is completely focused on saving his marriage to Liberty Ross - who played Kristen's mother in the movie - and so studio bosses will find a new director.

"The script has already been written and production will begin late next year. However, Rupert Sanders definitely won't be a part of the project. Rupert didn't want to be a part of it to begin with because he is desperately still trying to save his marriage. The search is still on for a new director," a source said.

It was previously reported that Liberty, 34, gave her husband an ultimatum after he cheated, telling him he could not be involved with the sequel if he wanted to be with her. "Liberty let it be known in no uncertain terms that Rupert can't direct the sequel to Snow White and the Huntsman," a source previously said.
