Mamas to be Rock! Didn’t you know? And if you didn’t you haven’t seen the photos of a very pregnant Christina Aguilera rocking it out, energetically while headlining at the New Orleans Jazz Festival this weekend, Friday May 2.

She covered her growing bump with an oversized white collared shirt and wore what looks like a fitted black dress with jeweled embellishments underneatth and jeweled shear body tights.

Aguilera and her fiance Matthew Rutler, a financial jouranlist, are expecting their first baby together. This will be his first and her second. She has a 6-year old son, Max, with ex-husband Jordan Bratman.
