Bionic Woman Christina Aguilera
As one of the finest voices of her generation, Christina has been belting it out since she was 6 years old.
Christina took time off after her third album, Back to Basics, to enjoy life with her husband, music executive Jordan Bratman. She's also been busy raising their 2-year-old son, Max, and decorating their Beverly Hills mansion once owned by Ozzy and Sharon Osbourne.
Now, Christina is back with her fourth studio album, Bionic.
