Listen to Kelly Clarkson on iHeartRadio

Kelly Clarkson

Kelly Clarkson would be the first to admit it -- she's a changed woman since she's become a mom.

Kelly appears on the cover of the next People magazine, and inside she says, "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, and have this whole other thing going on... I guess the biggest success I want is that whenever I die, people will say, 'She was so successful as a mother and as a wife.' That’s kind of my big goal.”

River, Kelly's daughter with hubby Brandon Blackstock, is now eight months old. She's also stepmom to Brandon's two older kids.

The issue of People with Kelly on the cover hits newsstands Friday.
