Christina Aguilera has a "little diva" on her hands.

The 34-year-old singer shared a photo -- the first -- of her baby girl, Summer Rain:

Aguilera and her fiance, Matt Rutler, welcomed Summer Rain (their first child together) on Aug. 16 in Los Angeles.

Rutler and Aguilera met in 2010 on the set of "Burlesque," where Rutler had been working as a production assistant.

Aguilera is also mom to 7-year-old son, Max, with ex-husband Jordan Bratman.

She'll return to "The Voice" on Feb. 23, serving as a coach alongside Blake Shelton, Adam Levine and Pharrell Williams.
