Hours after E! News confirmed the four-time Grammy winner welcomed her first child with fiancé Matthew Rutler, Aguilera revealed her baby girl's name via Twitter Sunday. The couple's newborn daughter joins Max, 6, the singer's son from her previous marriage to music exec Jordan Bratman.
"So proud to welcome our beautiful daughter Summer Rain Rutler into the world," Aguilera tweeted.
The diva did not disclose other birth details, such as her daughter's weight or measurement. Aguilera delivered her daughter at Cedars-Sinai Medical Center in L.A. The "Just a Fool" singer's pregnancy was revealed in February, a week after Aguilera announced her engagement to Rutler, a movie producer.
The future spouses met on the 2010 set of Burlesque, Aguilera's big screen debut.
Prior to welcoming her first child with Rutler, a heavily pregnant Aguilera posed nude for V this summer. "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," the 33-year-old pop star told the magazine.
