Christina Aguilera and fiance, Matthew Rutler, have welcomed a baby girl, a source confirmed to E! News on Sunday.
This is the second child for the pop star and part-time coach of NBC's "The Voice." She also has a 6-year-old son, Max Bratman, with ex-husband Jordan Bratman. Aguilera gave birth on Saturday, the source said.
The singer has occasionally been spotted flaunting her bun in the oven in Los Angeles. Shutterbugs even caught a sweet photo of Xtina's little boy protectively shielding his mama's baby bump while walking through paparazzi.
"Max already protecting mommy & his little sister! He's the greatest #maxthegreat," Aguilera captioned the photo, that had the text "big brother love" on it, on Twitter.
She and Rutler had celebrated their daughter's imminent arrival recently with a co-ed baby shower held at the home of the singer's stylist. Nearly 50 family members and close friends attended the intimate gathering, which was humorously highlighted with a cake that was one for the books.
Their tasty treat was decorated with a figure of a woman (presumably Christina) giving birth on a rug atop a hardwood floor, the baby's head (complete with a full head of hair) poking out from you-know-where.
"Push Xtina, push," the writing on the cake encouraged. "Christina is doing great," a source has told E! News. "She's really glowing. She's feeling great and isn't tired at all. She can't wait to meet her baby girl."
On Monday, she shared a sweet pic of herself putting a pair of headphones on her baby bump.
"Baby girl getting first listen to what mama's been creating in the studio," she said.
