Kelly Clarkson will take over Ellen DeGeneres' slot on US daytime TV, network NBC has said.
It was announced earlier this month thatwould come to an end next year after 19 seasons.
DeGeneres, one of the biggest names in American showbiz, had been rocked by allegations she presided over a toxic workplace environment.
NBC said— now in its second season — will replace DeGeneres' programme from autumn 2022.
Clarkson's programme is owned and produced by NBC's syndication arm.
Tracie Wilson, executive vice president, NBCUniversal Syndication Studios, said: "Kelly and our entire production team put their heart, intent and incredible passion into making a show that resonates with people of all ages, cultures and backgrounds.
Singer and TV presenter Clarkson, 39, got her big break after winning the first season ofin 2002.
DeGeneres, 63, revealed she was stepping down earlier this month and said the decision was driven by "instinct".
The host said she had known she would walk away after 19 seasons when she signed her most recent deal two years ago.
DeGeneres, who has been married to actress Portia de Rossi since 2008, also dismissed claims she was quitting due to the toxic workplace allegations.
Senior producers on the show were sacked last year and DeGeneres apologised to her staff after an internal review by Warner Bros found "deficiencies related to the show's day-to-day management".
The Ellen DeGeneres Show premiered in 2003 and will end in spring 2022.
