It's a boy for Christina Aguilera! Or at least it will be when the soulful singer gives birth later this year.

OK! has learned that Xtina's closest pals are all shopping for some pretty gender-specific gifts. "They're all boy-themed, all blue," a source reveals to OK!.

While Christina and hubby Jordan Bratman have yet to confirm that her growing belly bump is actually a baby, Ken Ehrlich, executive producer of this year's Emmy telecast, let it slip to OK! last week when he said, "We're very sensitive to her pregnancy."

A few days earlier, Paris Hilton called Christina "the most beautiful pregnant woman in the world" at a pre-VMA party hosted by the mom-to-be.
