The "Beautiful" singer opened up for the first time about how life has changed since she and fiance Matt Rutler welcomed their 5-month-old daughter, Summer Rain.
"I have a chill baby, she's just so calm and so easy to make laugh and smile, she's just a breeze, thank God!" she told "Extra's" Renee Bargh.
And although we haven't seen the little one's face, "The Voice" judge said her baby girl is absolutely adorable. "She's just so beautiful, these big blue eyes, she's just so gorg...very happy and feel very blessed having Summer Rain in my life," she gushed.
So, how has son Max, 7, reacted to his little sister?
"He's just so endearing and sweet to her. The only thing, I'm like, 'Wash your hands before you touch the baby'… you don't want the germs," Xtina explained.
"He's in school, he's 7, there's a little age gap, but it's perfect though, because then they don't fight over toys. But he's the big helper and the big teacher, so he's awesome. He's just so loving and sweet," she added.

Juggling two kids and a return to "The Voice," the blonde bombshell has her hands full. But, don't worry, her busy schedule won't stop her from getting in the studio.
"It's genuine and it's heartfelt and I'm very excited to pour my heart out into this record fully," she explained. "I've been gathering and writing and coming up with these amazing ideas for different parts of how I was feeling the past year, so I'm really excited to vocalize all of it and make it all come together."
