Congratulations are in order for "The Voice" judge Christina Aguilera. The "Beautiful" singer and her fiancé Matt Rutler welcomed a baby girl on Saturday, according to US Weekly.

New mommy Aguilera has been quite busy this week. In addition to the arrival of her new daughter, the 33-year-old singer tweeted a photo of herself in the studio on Monday, recording her latest album.

"Baby girl getting first listen to what mama's been creating in the studio" posted the star.

Aguilera poses in the picture holding her baby bump, a set of headphones cradling her stomach.

In April, Billboard reported that Aguilera was working on a follow-up to her 2012 album "Lotus" after the star wrote on Twitter:  

"So blissful in taking this time for creating all things blossoming new on the horizon...album, baby & beautiful music to come."

The future release date of Aguilera's eighth studio album has yet to be announced.

As for the diva's most recent news, US Weekly reports that Aguilera gave birth to the baby girl at Cedars-Sinai Medical Center in Los Angeles. Christina and Rutler have yet to release the name of their daughter.

Aguilera also has a 6-year-old son named Max with ex-husband Jordan Bratman.

The singer recently made headlines when she posed nude with her baby bump for V Magazine.

 "As a woman, I'm proud to embrace my body through all stages of life, staying fearless and confident in surrendering to the unknowns the future has in store," Aguilera stated in the magazine interview.

Just before word came that Christina had given birth, a source told E! News that the celeb was "glowing."

"She's feeling great and isn't tired at all," said the source. "She can't wait to meet her baby girl."
