Los Angeles: Actress Kristen Stewart wants to shave and tattoo her head, but she is yet to decide on the design she wants."I'm definitely going to shave my head before I die. I will definitely tattoo my head while it's shaved before my hair grows back. I'm not sure which part, probably the bottom quadrant in the back. I don't know what the tattoo would be, yet. Still thinking,” contactmusic.com quoted Stewart as saying.The "On The Road" actress has to keep her long brunette locks for parts in movies, but if she had her way, she'd sport lots of crazy hairstyles and colours."If I wasn't an actor, I would definitely do things to my hair. I would cut it more, I would dye it more. At some point I want to do a total boy cut, completely - not a pretty, girly version - like a straight up James Dean haircut," she added.
