Both singers will make their 'Dick Clark's Rockin' Eve with Ryan Seacrest' debut performances at the end of this year, joining Drake and Ne-Yo.
The already-crowded performers list of "Dick Clark's Rockin' Eve with Ryan Seacrest" becomes longer with the addition of two more musical guests Ke$ha and Taio Cruz. This will be the first time both of them sing at the Rockin' Eve concert.
"Ke$ha and Taio have had some of the year's most popular hits, and we are excited to welcome them to our New Year's Rockin' Eve' stage," producer Larry Klein said. "Taio and Ke$ha's energy in Times Square is going to be awesome. Their performances will be a great way to enter into the new year."
The previously-announced stars scheduled to rock the event are Jennifer Hudson, Willow Smith, Ne-Yo, Avril Lavigne, Drake, Jason Derulo, La Roux, Mike Posner, Natasha Bedingfield, Far East Movement and Train.
Dick Clark and Ryan Seacrest will host the show live in New York with Jenny McCarthy on hand as a correspondent at Times Square. Meanwhile, Black Eyed Peas' Stacy Ferguson aka Fergie will host the Los Angeles-based portions of the specials.
This New Year's Eve celebration will feature three and one-half hours of special performances. It will additionally include reports on New Year's celebrations from around the globe as well as the American tradition of Dick Clark counting down to midnight from Times Square in New York City.
