2. Christina Aguilera - Stripped (2002)

Stripped was Christina Aguilera's way of taking control of her musical career. With this album, she shed her teen idol image and showed us her alter ego, Xtina. Christina set the trend for other stars to let go of their teen idol stigma and embrace a new grown-up status (Miley Cyrus, anyone?). Stripped received several Grammy nominations and brought home one win.
