Robert Pattinson and Kristen Stewart aren't the only "Twilight Saga" stars keeping busy.  Ashley Greene, aka vampire Alice Cullen, has just booked another new role, that of a rebellious teenager in the Weintstein Company comedy "Butter." 

Produced by and starring Jennifer Garner, "Butter" follows the drama that unfolds when a small town gets a little too competitive about its annual butter-carving contest.  According to The Hollywood Reporter, production will begin next week in Louisiana.

Greene recently finished the Warner Bros. thriller "The Apparition," appeared in the Sundance drama "Skateland" and will return alongside her "Twilight" co-stars for "Eclipse" this June.
