As the brilliant Katie Couric nears the end of a five-year contract that paid her $15 million this year alone, sources tell me the former queen of morning TV is already mapping out her next job: filling the talk-show void when Oprah ends her show.

"No doubt, Oprah leaving her show is going to cause a huge gap in daytime talk, and the only person who could hope to fill her shoes is Katie Couric," a TV insider tells me. "Katie is going to bolt CBS News when her contract expires and start a new chapter of her TV life. Everyone knows she has the talent; now it's just finding the right show for her to do and surrounding herself with the best people to pull it all together."
