Christina Aguilera already has a multitude of hit albums and a successful stint on "The Voice" under her belt. The superstar singer is, however, willing to branch out further into acting if the right "crackhead" role comes along.

Aguilera sat down for the Billboard and Hollywood Reporter 2012 Film & TV Music conference on Thursday and talked about appearing on the silver screen again, E! News reported. "I do want to do more acting," Aguilera explained when her 2010 film "Burlesque" was mentioned. "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."

She wants it to be the right role. "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."

Aguilera a crackhead? That would certainly be a step in a different direction. The "Voice" mentor starred in "Burlesque" as quintessential small-town girl Ali, who quits her job at a bar, ventures to Los Angeles and decides to pursue a career on the stage.

A darker role wouldn't be that far-fetched, though. Aguilera plays a sexy serial killer in her video for "Your Body," seducing men and then slaughtering them.

The tough-talking mom also recently bared her teeth to the media when she lashed out at tabloid "trash." At the Thursday conference, Aguilera said she doesn't read blogs. "It’s just God-knows-who in buttf--k wherever writing hate sh-t," she said, adding, "You can’t take it seriously. I’m sure you’ve all been hated on at some point by buttf--k people."
