Suddenly, there's a whole new meaning to "Come On Over Baby" for Christina Aguilera.
The five-time Grammy winner and hubby Jordan Bratman have welcomed their first child in Los Angeles.
Aguilera delivered "a beautiful, healthy baby boy," Max Liron Bratman, Saturday at 10:05 p.m., according to a statement from her rep.
The child weighed six pounds, two ounces and measured 20.5 inches. "Mom is resting and doing well!" Aguilera's publicist proclaimed.
A source close to Aguilera confirmed to E! News that the entertainer gave birth via C-section. "She will be in the hospital for a few days," the source said, "but she's feeling fine." (E! Online was the first to report Aguilera was prepared to have a C-section.)
The singer adorned her Website with blue balloons heralding her special delivery.
"Today is a very joyful and special day for Jordan and I as we welcome our first son into this world," Aguilera wrote in a message to fans.
"In honor of our love for each other and our growing family, I have put together a special video for the song 'Save Me from Myself' off my Back to Basics album. This video is very dear to me as it includes actual footage from our personal wedding video!
"Just a little something to say 'thank you' for your undying love and support. It is in no small part because of you that I live such a blessed and wonderful life!" (Apparently, not even the prospect of dirrty diapers can dampen their spirits.)
The couple seem to have jumped the gun a bit, as a quick text message to friends and family, sent around 4 p.m. Friday, announced: "Baby has arrived. Mom and dad are doing well!"
While E! News was able to confirm the impending stork delivery last July, Aguilera herself, despite an ever-expanding midriff, didn't publicly acknowledge the pregnancy until early November, when she told 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, never revealing to press either the babe's due date or gender along the way.
Unfortunately, she failed to share the keep-mum edict with pal Paris Hilton, who back in September publicly congratulated the "most beautiful pregnant woman in the world" while hosting an MTV Video Music Awards party at Las Vegas nightclub LAX.
In early November, Aguilera held the first of three scheduled baby showers at her Beverly Hills home, wherein we got the first clue about the baby's sex: All of the guests' baby gifts had a decidedly blue bent.
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.
