What Dr. Fisher says:
"
Joel Madden's tattoos and lyrics show his creative side. He is an explorer, irreverent and risk taking, which is probably what makes him so charismatic. However,
Nicole Richie, despite her run-ins with the law and substance abuse, is deeply rooted in family and instinct and these altruistic qualities as well. Nic's emotional expressiveness makes her a Negotiator. Joel's ex,
Hilary Duff, is a Negotiator -- just like Nicole -- expressive, curious and imaginative. Joel clearly goes after the same type of girl, but Nicole has a riskier Explorer edge to her, which is what won him over in the end."
