Katie Couric is expected to say "I do" or "buzz off" this week to CBS.

Sean McManus, the new CBS News boss, has indicated to pals that he expects to finally hear a yes or no from the perky "Today" show host in the next few days as to whether she wants to take over Dan Rather's old anchoring job on the "CBS Evening News," reports the industry trade magazine Broadcasting & Cable.

Couric, whose four-year $60 million NBC deal expires this spring, is expected to command at least $20 million a year from CBS if she joins the last-place newscast.

A salary of that size would land Couric among the top paid network TV hosts, third only to Jay Leno and David Letterman.

In recent weeks, CBS has confirmed that network brass has been in talks to lure Couric away from "Today," although insiders say they are confident that Couric will remain with NBC.

Her exit would deal a serious blow to "Today," which has been the top-rated morning show for the last 10 years.

If Couric were to leave, the leading candidates to replace her are "Dateline" and "Today" correspondent Ann Curry, "Nightly News" correspondent and "Today" weekend co-anchor Campbell Brown, and "Today" co-host Alexis Glick.

Couric has extremely strong ties to NBC. The network's chief, Jeff Zucker, is a longtime friend and the former executive producer of "Today." He is also considered one of the few producers with whom Couric -- long said to have a "difficult" and "diva-esque" personality off-camera -- has gotten along over the years.

In recent times, she's come under extreme scrutiny for those alleged traits, and starting fresh in the evenings might be considered a good way for her to rebuild her image.

Landing the high-profile anchor job at CBS would also give Couric a change of pace for the first time in more than a decade, allow her to help reshape a news organization that is struggling to reinvent itself in the wake of last year's memogate scandal and give her a chance to sleep late for the first time in years.
