Christina Aguilera & Maroon 5 Liven Up the 2011 AMAs

Livening things up the moment they stepped onstage, Christina Aguilera joined Maroon 5 for a performance at the 2011 American Music Awards in Los Angeles, CA on Sunday night (November 20).

Bringing the Nokia Theatre LA Live crowd to their feet, the "Bionic" beauty powerfully belted out "Moves Like Jagger" alongside Adam Levine, Jesse Carmichael, Michael Madden, James Valentine and Matt Flynn.
