Christina Aguilera’s baby boy joy

Christina Aguilera and Nicole Richie both had babies on Friday.

The five-time Grammy winner Aguilera and husband Jordan Bratman welcomed their first child in Los Angeles on Friday at the same hospital as Richie, Cedars-Sinai..

The couple announced the birth in a quick text message to friends and family around 4 p.m.: “Baby has arrived. Mom and dad are doing well!”

There were no further details immediately available. “As soon as I have more information I will let you know,” the singer’s rep said.

Aguilera revealed her pregnancy to Glamour magazine she would “enter into mommyhood” sometime in 2008.

The 27-year-old onetime Mouseketeer has kept a relatively low profile throughout her pregnancy—aside from the now-requisite nude-and-pregnant spread in this month’s Marie Claire—opting to keep the details of her firstborn a secret.

In early November, Aguilera held the first of three scheduled baby showers at her Beverly Hills home.

Aguilera told Marie Claire this month that she and hubby Bratman, a 30-year-old music-marketing exec, always had plans to start a family but were nonetheless surprised when they learned a baby was already on board.

“We were planning on starting to try after the [Back to Basics] tour,” she said. “And so, I had gone off the Pill to prepare my body, because I didn’t know how much time it would take. You’ve heard it takes some time—except with Power Egg and Super Sperm here. I’m like, ‘Oh my God, can you believe it just happened?’ “

Aguilera and Bratman tied the knot in Napa Valley, California in November 2005 after three years of dating.
