Christina Aguilera debuts the first pictures of 5-month-old Summer Rain Rutler

Nearly six months after welcoming daughter Summer Rain Rutler with fiancé Matthew Rutler, Christina Aguilera shared the first pictures of the little girl’s face… And just two words immediately come to mind: Those eyes!

“She was literally like an angel… We had an immediate calm bond, and I felt unexplainably connected to her and her spirit,” Christina told People, which shared more portraits. “Her smile lights up a room and I know it melts mama and daddy’s hearts.”

Christina added Summer Rain and 7-year-old Max are “the center focal piece” in her life, which is pretty busy these days. Not only is she returning to The Voice as a judge, but she’s also working on a new album and developing a show for ABC Family. That all makes for quite the juggling act.

“‘Mom guilt’ is the worst thing ever,” Christina said. “But you have to surrender and let go, knowing you’re doing your very best and no one loves them, or wants what’s best for them more than you.”
