Clarkson and Blackstock married in 2013 and welcomed River the next year. The singer cited a happy marriage and family as her biggest goal in a 2015 interview with Elle magazine.

"I think, especially in this society today, it's really hard to have a successful marriage," she explained. "Especially for people in the public eye. It's hard to have a successful marriage and be successful as a parent while wanting to have a career."

"I just want to be the best mom ever and I just want to be successful at being a wife. Always be loving and supporting. It's all very selfless," the star said. "I'm 32. It's time for that."

Clarkson came to fame by winning American Idol Season 1 and has since released seven studio albums. She last released Piece by Piece in 2015, which debuted at No. 1 on the Billboard 200.
