Mariah Carey, we love you. We celebrate your whole catalog, from "Vision of Love" to your latest, "Memoirs of an Imperfect Angel." We're even kind of obsessed with your fragrances, especially the sweet chic "Lollipop Bling." But most importantly, we love you and Nick and we're thrilled to death over your pregnancy! So that your little baby one day understands what a mane maven his/her mama is, we'd like to take a look back and some of your most fabulous hair moments. Aspiring divas, take note.
