Christina Aguilera and fiance Matthew Rutler revealed on Sunday they had named their newborn daughter Summer Rain Rutler.

In a tweet, the singer wrote, "So proud to welcome our beautiful daughter Summer Rain Rutler into the world."

The "Just For You" singer gave birth to her daughter on Sunday at Cedars Sinai in Los Angeles. She arrived early on Saturday and then gave birth via C-section.

Summer Rain is Aguilera's first daughter with Rutler. They got engaged earlier this year on Valentine's Day after meeting four years ago while she was filming Burlesque.

The singer posed nude recently for V Magazine. In the photoshoot, Aguilera was joined by her film producer fiance, while she alternated between going nude and wearing a white maxi dress.

She explained to the magazine during the shoot, "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 has one previous child, a 6-year-old son, named Max, with her ex-husband Jordan Bratman.
