Christina Aguilera, who will be returning to The Voice for Season 8 after being absent for two editions, is just crazy about her new little girl Summer Rain and is doing her best to juggle motherhood with career opportunities.

Aguilera and her fiance Matt Rutler welcomed Summer Rain in August 2014.

"I was speechless," the 34-year-old singer told People in a cover interview for its latest issue. "She was literally like an angel... We had an immediate calm bond, and I felt unexplainably connected to her and her spirit."

The couple's little girl is now six-months-old. She has a big brother Max Liron, 7, whom Aguilera had with her ex-husband Jordan Bratman.

"Her smile lights up a room and I know it melts mama and daddy's hearts," Aguilera said. "She laughs a ton and is easy to make smile. She just wants to be where the action is!"

Aguilera, who won a Grammy award on Sunday for Best Pop Duo/Group Performance for "Say Something" with A Great Big World, reportedly has some other professional pursuits underway, like recording a new album and producing an upcoming ABC Family television series.

"It's definitely not easy juggling work and motherhood, as being a parent is a full-time job within itself," she explained. "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."

Aguilera admitted being a parent is not easy but she's obviously up for the challenge.

"It's hard to know you won't have all the right answers at the right times. And 'mom guilt' is the worst thing ever," Aguilera told People. "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. They are the center of my universe."

Aguilera will serve as a coach on The Voice next season alongside Pharrell Williams and mainstays Adam Levine and Blake Shelton when it premieres February 23 on NBC.
