Christina Aguilera is showing off her voluptuous body and amazing pipes during the Burlesque performance at the American Music Awards.

She may be going through a difficult time with her personal life, but this hot mama is definitely putting all of her energy into her craft, and it shows.

We were already excited to see Burlesque with Xtina, Cher and Ryan Seacrest's main squeeze Julianne Hough, but now we're REALLY pumped to see these ladies on the big screen ... shaking their moneymakers.

Loves it!
