Yesterday, when Matt Lauer teased the fact that Katie Couric was coming on Today this morning to make a "major announcement," rumors were flying. Was she going to announce that she was leaving CBS? Going to CNN? Returning to Today for good? Turns out: No, no, and no. Check out the video...

Couric was back on her old stomping grounds to promote Stand up to Cancer, a telethon that she will host this September along with ABC World News anchor Charles Gibson and NBC Nightly News anchor Brian Williams. Not juicy gossip, but a very good cause.
