Christina Aguilera shares first picture of her daughter

Christina Aguilera, 34, chose an imaginative way of introducing the infant to fans as she took to social media on Sunday.

Sharing a snap of her baby daughter lying on a fur blanket, she tweeted: 'Watch out...another one's getting ready to conquer the world! #driven #diva2.'

Summer is pictured lying away from the camera, clad in a pink dress, her bloomers reading Lil' Diva. 

The baby is Christina and her 29-year-old fiancé Matthew Rutler's first child together, joining the singer's son Max, seven.

Max was born during Christina's first marriage to Jordan Bratman.
