Kelly Clarkson Sets the Record Straight on Her Name Change: ‘Too Late’ To Go by Kelly Brianne Kelly Clarkson was on the red carpet for the American Song Contest. She was asked about changing her name to Kelly Brianne. She said she recently got divorced so she dropped her married last name. That left her with her first and middle name Kelly Brianne. She said she will always be Kelly Clarkson. I don’t think I can change Clarkson at this point. I’m 20 years in.
