If being vanilla means never being arrested for a DUI and having her mugshot posted all over the news and internet, then Carrie is the "vanilla-iest of all." She'd never be so careless and irresponsible as Wynona was. She's gained 200 pounds, her personal life is tabloid fodder, and her music isn't so exciting! Let those without sin cast the first stone, Wynona.
Leave Carrie alone.
