Christina Aguilera has always been known as a creative artist. And it was no different Sunday night when X-Tina named her daughter Summer Rain Rutler . “Christina wanted something different and unique for the baby’s name,” a source tells E! “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.”
