Kelly Clarkson officiated a surprise wedding during her New Year's Eve Las Vegas residency show for a gay couple named Brian and Marcello, who had been together for 14 years and were celebrating their 15th anniversary in January. The couple, who initially planned to get married later in 2024, exchanged vows mid-performance, marking the first time a wedding has taken place during one of Clarkson's shows. Despite her recent personal struggles and divorce from ex-husband Brandon Blackstock, Clarkson's role in the couple's union highlighted her positive stance on love and personal growth.
