Singer/actress Ashanti has joined the cast of the 20th Century Fox film "John Tucker Must Die." Described as a high school take on "The First Wives Club," the film revolves around a trio of girls from different social groups who band together to seek revenge on the school's resident stud who has broken their hearts.

They set him up to fall for the new girl in town, just so she can dump him and break his heart. Ashanti will play one of the trio.

Sophia Bush (WB Network's "One Tree Hill") already has been cast as one of the trio, while Brittany Snow (NBC's "American Dreams") plays the new girl in town. Jesse Metcalfe (ABC's "Desperate Housewives") will play the title character.

Ashanti recently starred as Dorothy in ABC's "The Muppets' Wonderful Wizard of Oz" and earlier this year appeared in "Coach Carter."
