Christina Aguilera could be having a son ?? Blue stands for boys and pink is for girls.

Christina Aguilera celebrated her pending motherhood with a baby shower on Saturday at her home in Beverly Hills.

The shower, the first of three planned for the expectant mom, according to a source, was an intimate gathering of close friends and family.

Though the singer has not confirmed the gender of her baby, there was a distinctive theme to the gifts – the color blue.

Among the presents bought from baby boutique Bel Bambini, where the singer set up her registry last month, were a blue Loved Mom Guitar shirt, a Cariboo bassinet with blue dot bedding, Trumpette Johnny’s socks – and Sozo Whiz Kid wee block, meant for use when changing a baby boy’s diapers.
