Aguilera, 34, welcomed Summer with her fiance Matt Rutler in August, last year. Since then, she has been working on her new album and preparing for season 8 of 'The Voice', where she will appear as a coach, reported Us magazine.

"Watch out... Another one's getting ready to conquer the world! driven diva2," she captioned the photo of her little girl in a hot pink dress and white frilled diaper that had 'Lil Diva' stitched onto the back.

Aguilera is also mother to seven-year-old son Max with her ex-husband Jordan Bratman.
