The story revolves around a young woman (Bell) who discovers that her brother is planning to marry the girl who bullied her throughout high school, forcing her to try and prove the bride-to-be's true colours.
Race To Witch Mountain director Andy Fickman is helming the project, which is based on a screenplay by Moe Jelline.
Production is slated to begin in Los Angeles in late summer.
Bell recently wrapped production on another Disney comedy, When In Rome. She will also star in forthcoming manga adaptation Astro Boy and the Jon Favreau-scripted comedy Couples Retreat.
