There are so many different ways to develop a character - physically, mentally, spiritually and all of that - but the research was really beautiful.

I've been rapping since I was 18 years old, with a crew called Blades.

I play the keyboard, piano - I like making beats.

I'm pretty unusual for an actress in Hollywood because I am totally unselfconscious about my body.
