Ashlee's Second Act

MISS METAMORPHOSIS

Simpson is constantly experimenting with her look, evolving from funky (left, in 2004) to sophisticated (in Giambattista Valli at the VMAs). And she's gone back to being blonde: "I was really sick of getting my roots done – it looked like I was balding when they'd come in." She admired Gwen Stefani's platinum tresses so much that she even used the singer's colorist.
