Christina Aguilera wants to play crackhead in next film

London: Pop star Christina Aguilera says she wants to prove her acting skills by playing a junkie in a "crazy and meaty" new film role.

The `Dirrty` hitmaker last appeared on the big screen in 2010`s movie musical `Burlesque` alongside Cher, but now she wants to land a darker role, reported a leading daily.

"I do want to do more acting. I want to do something where I can really sink my teeth into something a little more challenging. Really outside of myself, outside of music.

"I sort of had this personal aspiration to do film, but I said, `I never want to do a musical! It`s too much like myself`. I want it to be honest and genuine in expanding my wings and doing something really, really different. A crackhead on the street or a drug addict. Or something crazy and meaty and juicy. Something that really took me out of myself," she said.
