Christina Aguilera Introduces Daughter Summer Rain On People

Meet Christina Aguilera‘s mini-me!

The 34-year-old, six-time Grammy Award winner and her 5-month-old daughter, Summer Rain Rutler,pose on the cover of People magazine’s Feb. 23 issue, on newsstands Friday. It’s the first time the “Say Something” singer has given the world a glimpse of her firstborn daughter with fiancé Matt Rutler.

(The diva has a 7-year-old son, Max Liron Bratman, from a previous marriage.)

After Christina gave birth on Aug. 16, 2014, “I was speechless,” the singer recalls. “She was literally like an angel…We had an immediate calm bond, and I felt unexplainably connected to her and her spirit.”

What’s Summer like today? “Her smile lights up a room and I know it melts mama and daddy’s hearts. She laughs a ton and is easy to make smile. She just wants to be where the action is!” Christina gushes.

The action seems to be with big brother Max. “They are the center of my universe,” she tells People.

Christina took a break from NBC’s The Voice to focus on her kids, but she’ll return for Season 8 on Feb. 23. “It’s definitely not easy juggling work and motherhood, as being a parent is a full-time job within itself,” the “Beautiful” singer confesses. “You just have to make it work for you. My life has so many different moving parts, but my kids are the center focal piece, and everything else shifts around them.”

“It’s hard to know you won’t have all the right answers at the right times,” Christina adds. “And ‘mom guilt’ is the worst thing ever.” Over the years, however, she learned “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.”

Earlier this week, Christina opened up about her daughter to E! News.

“She’s just gorgeous. She’s so beautiful and she’s so peaceful and awesome and just a gem. She really is,” she said. “Just loves life!”

Max “loves being a big brother,” Christina added. “I have no complaints. Beyond my expectations. He’s like an old grandma coming in the room. He’s 7 and he was just so engaged with her.”
