Beginning Sept. 12, Gifford will appear at least two days a week to cover "big name celebrity interviews and the Broadway beat," Paramount Domestic Television announced Monday.
Gifford was co-host of the syndicated "Live With Regis & Kathie Lee" (search) with Regis Philbin for 15 years. She left the show five years ago.
"Being a member of 'The Insider' family gives me an opportunity to do what I know, television, with what I love, theater," Gifford, 52, said in a statement. "I'm looking forward to finally casting a well-deserved spotlight on the world of theater. And it's no secret that I love to talk, but the real secret is I love to listen, too."
