Aguilera expecting a baby boy?

Christina Aguilera has received blue-themed presents at her baby shower, sparking rumours that she is expecting a boy.

The singer held the first of three parties at her Beverly Hills home on Saturday, with guests including Gwen Stefani and her husband Gavin Rossdale.

The 26-year-old announced that she is pregnant by husband Jordan Bratman earlier this month after reports began circulating as far back as February.

Aguilera, who is due to give birth early next year, has not confirmed the sex of her baby. However, People reports that most of the gifts were blue, suggesting that a son is on the way.
