Amanda Bynes -- Pretty, Pretty Princess Wigs

Amanda Bynes has a serious addiction and TMZ has learned she just got herself another fix -- no, we don't mean drugs ... we're talking WIGS.

Bynes recently placed an order from Couture Princess Wigs for three Disney-inspired wigs -- one Cinderalla, one Barbie, and one Belle. She placed the order the day of her arrest and three wigs cost her a total of $830.00 (that includes shipping).
