Christina Aguilera celebrated the first birthday of her daughter Summer Rain on Sunday. The “Beautiful” singer and fiance Matt Rutler both shared birthday wishes and adorable photos of their baby girl via social media in honor of her big day.

Instagram was Christina Aguilera’s forum of choice for sharing her birthday love.

“Happy 1st Birthday! My Sweet, Summer Rain,” she captioned the photo.

Many fans have wondered about the inspiration behind Christina Aguilera and Matt Rutler’s unusual choice of baby names.

“Christina wanted something different and unique for the baby’s name,” a source told E! News last summer, shortly after the baby was born. “She loves how Summer Rain Rutler flows together and thinks summer is an amazing time of the year. She has always been a more expressive person and a little bohemian who is inspired by words and daily life.”

Christina Aguilera will hopefully get to spend some more time at home with Summer Rain, as she isn’t coaching on this upcoming season of The Voice. Gwen Stefani will take her place, alongside Adam Levine, Blake Shelton, and Pharrell Williams.

Aguilera is also mom to son Max from her marriage to Jordan Bratman.
