Katie Couric and Matt Lauer will reunite when the 'CBS Evening News' anchor drops by her old stomping grounds at the 'Today' show to promote her new book on Wednesday morning.

According to The Hollywood Reporter, Couric will chat with Lauer about her book, 'The Best Advice I Ever Got: Lessons From Extraordinary Lives,' which comes out tomorrow.

Beyond their mini-reunion Wednesday, Couric and Lauer could form a long-lasting partnership again. The New York Times is reporting that Couric could recruit Lauer for the syndicated talk show she'll almost certainly start up after she leaves her current anchor post when her contract expires in a few months.

A rep for NBC's 'Today' told AOL TV, "There have been a lot of rumors and speculation circulating through the press, and we'd prefer not to comment on any of it. Matt Lauer is under contract with NBC News for a long time."
