The 32-year-old singer opened up about the infant in an interview for the March 3 issue of People. Clarkson gave birth to River Rose in June 2014, and is also stepmother to husband Brandon Blackstock's two other children.
"My whole life took a big 180," she revealed. "I never thought I was going to be a mom, so it's very much changed my world in the most awesome way. I love what I do, but I feel like I relied on my career a lot for my self-worth. And now I'm more than that. I'm a mother and a wife."
