The pregnant pop star showed off her blossoming baby bump in a form-fitting little black dress on Friday night at the New Orleans Jazz Festival.
The singer was full of energy as she pranced around the stage and belted out some of her biggest hits.
She performed for more than an hour. Talk about stamina!
Aguilera opened her long set with Nina Simone's "Be My Husband," according to the Times-Picayune newspaper.
The singer is expecting a baby with fiancé Matthew Rutler, and it's baby No. 2 for Aguilera and her first child with Rutler.
E! News confirmed they are having a girl. The songstress is already a mommy to 6-year-old Max, her son with ex-husband Jordan Bratman.
