Looking for the voice to be as close to Cristina Vee. However original takes are acceptable as well. 

As a succubus demon, Verosika is actively seductive and flirtacious, attributes she intigrates into her famous popstar persona as a means of manipulation. Despite her star-status, fame and confidence, Verosika also appears somewhat jaded and is nursing a drinking problem, something she has previously been to rehab for. She is capable of being petty and mean-spirited, as well as highly competitive. She doesn't take losing well, particularly to Blitzo, with whom she shares a romantic history - a relationship that did not end well and is implied to be a source of bitterness for her.
