Christina Aguilera is a brand new mama ... again!
The singer gave birth to her second child, a baby girl, on Saturday at Cedars-Sinai in Los Angeles via C-section.
"So proud to welcome our beautiful daughter Summer Rain Rutler into the world," Aguilera tweeted on Sunday.
The pop star did not disclose any other birth details, including her daughter's weight or measurement.
This is the first child for Christina and fiance Matt Rutler. Their newborn daughter joins Aguilera's son Max from her first marriage to Jordan Bratman.
The former "Mickey Mouse Club" star recently showed off all her pregnancy curves by going nude for V Magazine -- putting her baby bump on full display.
"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," she told the magazine.
Congrats to the couple on their little girl -- we can't wait to see the first photos!
