Kelly Clarkson will take over the slot left vacant by Ellen DeGeneres when she ends her chat show next year, NBC has said.
DeGeneres revealed earlier this month that she would end her show after 19 seasons on the network.
Although one of the biggest names in US entertainment, she became marred in allegations of workplace bullying, and accusations that she presided over a toxic environment for the staff working on her show.
The Kelly Clarkson Show, which is now in its second season, will take over the daytime chat slot in autumn next year.
Clarkson's show is made and owned by NBCUniversal, with whom Sky shares a parent company (Comcast).
Tracie Wilson, executive vice president of 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.
"We're working on some big plans for season three and are looking forward to becoming the premier show in daytime for years to come."

Clarkson, 39, is best known for winning the first season of American Idol in 2002, going on to have hits such as Since U Been Gone, Because Of You, and My Life Would Suck Without You.
DeGeneres, meanwhile, said she was stepping down from her show due to "instinct", admitting she knew when she signed on for her final two seasons that they would be her last.
The star, who is also well known as the voice of Dory in the Finding Nemo films, has batted away claims that the allegations of workplace bullying were behind the decision to quit.
DeGeneres's show will end in 2022.
