'Twilight' star Ashley Greene has joined the cast of Jennifer Garner's new comedy 'Butter'.

The Hollywood Reporter says the film, which is also being produced by star Garner, follows the contestants in a butter-carving contest in a small American town.

Greene, who plays Alice Cullen in the 'Twilight' movies, will play a rebellious student, Kaitlen Pickler, in 'Butter'.

Filming on 'Butter' begins next week in Louisiana.
