London - Christina Aguilera has given birth to a baby girl and has released her name on Twitter.
The 33-year-old singer welcomed her first child with fiancé Matt Rutler via Caesarean-section at Cedars-Sinai Medical Centre in Los Angeles on Saturday, according to UsMagazine.com.
The star took to Twitter to share her joy.
“So proud to welcome our beautiful daughter Summer Rain Rutler into the world,” she wrote.
The 'Your Body' hitmaker also delivered her six-year-old son Max - whom she has with ex-husband Jordan Bratman - via C-section and was reportedly keen to give birth to her daughter naturally this time around.
A source said earlier this week: "She's due at any moment. But she's freaking out because with her first child, Max, she had a C-section.
This time, though, she wants to have a natural childbirth."
The 'Voice' USA mentor announced in February she was expecting a baby with the production assistant.
The happy news came one week after Matthew proposed to the beauty in the backyard of their new home in Los Angeles on Valentine's Day.
Meanwhile, Christina recently showed off her pregnancy body in V magazine and admitted she is very "proud" of her figure.
She said previously: "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." - BANG Showbiz
