Clarkson, who wed talent manager Brandon Blackstock in 2013, welcomed their first child, daughter River Rose, last year. The 'Heartbeat Song' hitmaker is step mother to Savannah, 13, and Seth, 8, who are Blackstock's kids with his ex-wife.
Clarkson said she could not be happier with her blended family, reported People magazine.
"My best friend always say, 'You just want to create the family you never had.' I might be doing that. In defence of my family, it happens. People fall out of love, and people go separate way. People are human.
