She might have been secretive about her baby bump but Christina Aguilera did what a lot of celebrities do nowadays when it comes to announcing something personal: logging on to Twitter and posting a picture to validate a point. And that's what she did.


Christina Aguilera and Matthew Rutler met each other on the sets of Burlesque  

In the picture posted, fiance Matthew Rutler's hand is placed on Aguilera's growing belly as she smiles for the camera in NYC.

Aguilera is expecting a baby girl. She announced the child's sex during a concert in Malaysia last month but this is the first snap of her bump.
