R&B artist Robin Thicke is in negotiations to write his first film score for the urban drama, This Wednesday; his real-life wife Paula Patton is attached to star.

She'll play the title character, a female pimp and the 'trick baby' of a pimp father and hooker mother. The Hollywood Reporter adds with her best friend's support, she struggles to survive on the harsh streets of Philadelphia.

From writer-director Christine Crokos, the film is inspired by the true story of a female pimp in Atlanta; it will be expanded from her 2001 short Heroine Helen about the same character.

Shooting on This Wednesday is expected to begin late this year in Philadelphia.
