Christina Aguilera in ‘Rolling Stone’ in 2000

Christina Aguilera poses for Rolling Stone magazine in September of 2000, back when her brand was on the sassy teenybopper side of things. She has since matured into grande dame mode. Christina Aguilera was born in 1980, so she turned 20 the year this photo was published. The disc-shaped object in her hand is a portable CD player from the Before Times.
