Kelly Clarkson has revealed that she's not worried about turning 40 in April as each passing year has been "exponentially better" for her. The "Stronger" hitmaker plans to mark her big birthday with a series of celebrations over the summer, saying that it will be a "whole thing." She recently filed to legally change her name to Kelly Brianne after dropping her married last name following her divorce from Brandon Blackstock. Kelly is a coach on The Voice and also hosts her own talk show, The Kelly Clarkson Show. She is currently co-hosting the American Song Contest with Snoop Dogg.
