Her experience being pregnant with River Rose is one of the reasons she wants a boy next.
"Honestly the only reason I am hoping for a boy is because they usually say if you're sick with a girl, you won't be with your boy. And if you are sick with the boy, you won't be with the girl," she explained. "I'm purely hoping it is a boy so I can have the most magically wonderful pregnancy."
Little River turns one in June, and she couldn't be more adorable. Clarkson has been sharing photos of her everywhere from American Idol to the Tonight Show Starring Jimmy Fallon.
