One of the most accomplished performers of the last decade, Christina Aguilera has sold more than 30 million albums worldwide, achieved four No. 1 singles on the Billboard hot 100 chart, and has won five Grammy awards, as well as three top five albums in the United States. She has collaborated with Herbie Hancock, Andrea Bocelli, Tony Bennett, Elton John and The Rolling Stones. Aguilera was also the only artist under 30 to make Rolling Stone Magazine’s list of 100 greatest singers of all time. In 2010 Aguilera starred in her first feature film, “Burlesque,” opposite Cher and Stanley Tucci, earning a Golden Globe nomination for “Bound to You,” which she co-wrote and performed. Earlier that same year, Aguilera launched her new album, “Bionic,” collaborating with artists Sia, Le Tigre and Ladytron as well as producers Tricky Stewart and Hill/Switch. Christina is now one of the stars of NBC's hit reality competition "The Voice" serving as a coach and mentor for singers and competing against other teams led by fellow musical talents Cee Lo Green, Blake Shelton and Adam Levine.
