Christina Aguilera performs “Express” from her upcoming movie, Burlesque, at the 2010 American Music Awards held at the Nokia Theatre L.A. Live on Sunday (November 21) in Los Angeles.

The 29-year-old entertainer recently praised single mothers since recently becoming one. “My focus first and foremost is my son Max. More power to single moms and those out there doing it… At the end of the day, he’s the love of my life. I adore him and he’s such a character and he’s so happy and that’s what’s most important.”

Burlesque opens everywhere on Thanksgiving!
