Kelly Clarkson, 31, may have told Ryan Seacrest that she is "so over" planning her October wedding to fiancé Brandon Blackstock, but she loves her role as stepmom to his two children.

"I have a 12-year-old and a 6-year-old now," the "Because of You" singer said during Tuesday's "On Air with Ryan Seacrest." "It's so different, but it's perfect."

"I actually really dig the mom thing … I am quick to go, 'I told you not to touch that!'" she said. "I am totally my mom. My mom was a hard mom."
