Bloodthirsty (1999)

The tale of a young girl searching for acceptance and a place to live. When the petite rock star finds her way into the house of a nouveau vampire (all the bloodlust, none of the fangs or special powers), a bizarre relationship is formed. As the girl comes to accept the slashings and bloodletting in exchange for free rent, the vampiric seductress must decide whether it is safer for the relationship to continue or the new partner to be cut loose.
