Kelly Clarkson has officially changed her name to Kelly Brianne following her divorce from Brandon Blackstock. A judge in California granted her request on Monday, March 28. Clarkson initially filed for the name change last month, stating that it was for her personal life. She clarified in an interview that her public name would remain the same. The name change comes after her divorce from Blackstock, whom she was married to since 2013. Clarkson has also spoken publicly about her strained relationship with her late father.
