Rapper 50 Cent's ex-girlfriend, actress Elise Neal, has landed the lead in video vixen Karrine 'Superhead' Steffans' biopic.

Neal, who resembles the kiss-and-tell actress/author, jumped at the chance to play Steffans on the big screen after reading her expose Confessions Of A Video Vixen.

But she'll only take on the role if Steffans is 100 per cent behind her.

She tells King magazine, "I just want it to be something she has a lot of control over... I would do it if it came together the right way."
