According to Variety, Emma Roberts will star in teen fantasy-comedy Bras and Broomsticks for Fox 2000, with Susan Cartsonis (What Women Want) producing through her Store Front Pictures shingle.

The project's based on Sarah Mlynowski's book about an angst-ridden teenage girl who discovers that her socially inept younger sister -- and not she -- has inherited her divorced mother's magical powers. Despite the mother's warning not to cast spells, the younger sister succumbs to temptation, with disastrous results.

Roberts, the 13-year-old niece of Julia Roberts, is co-starring with Sara Paxton in Fox 2000's mermaid fantasy Aquamarine, which Cartsonis is producing. Elizabeth Allen is the director on Aquamarine, now shooting in Australia.
