Tonight will likely be the last time you'll get to hear Larry King mutter the words, "Go ahead, Topeka." That's because the venerable cable host ends his CNN show of 25 years tonight with the final episode of "Larry King Live."

Sure, the cynic in me says, "and not a moment too soon." But the king of fluffy (and often maddening) cable interviews, who has never been much on actually prepping for his interviews, certainly has his fans. And most of them are dropping in tonight to pay their respects.

CNN says Larry will have 15 surprise guests on tonight's show. Reports are that Diane Sawyer, Brian Williams, Katie Couric, Barbara Walters, Bill Maher, Ryan Seacrest, and Donald Trump will be among them.

British reality show judge Piers Morgan has been signed as King's replacement.

Tune in tonight at 9pm to see the final episode of "Larry King Live."

TheWrap.com is reporting that CNN is in negotiations with British television host Piers Morgan to replace Larry King on the network's primetime interview show.

King will step down from "Larry King Live" this fall.

Morgan is a judge on "America's Got Talent" and "Britian's Got Talent" and was also a winner on NBC's "Celebrity Apprentice."

So I guess CNN decided not to go the "journalist" route....

After starting my morning with a looking-darn-good, but sounding-awfully-creaky Whitney ("I never left") Houston, I ended my night by watching another singer on a kind of redemption tour.

Chris Brown, his mama Joyce Hawkins and his lawyer Mark Geragos appeared on 'Larry King Live' last night, not explaining what happened between Chris and Rihanna that fateful night.

Lord knows Larry tried. He pretty much asked the same questions for the hour, trying to get Chris to explain what happened that night and what set him off.

North Carolina Rising (8pm, UNC-TV) - A special compilation show highlighting some of the economic successes of rural North Carolina featured in the UNC-TV series "North Carolina Now." Look for reports on preserving coastal towns, revitalizing small towns, building for eco-tourism, and much more. 

Larry King Live (9pm, CNN) - Larry interviews Rihanna-beater Chris Brown, who appears with his mother and his lawyer Mark Garagos. Apparently, Brown at one point tells King that he shouldn't really talk about what happened that night (then why is he on there??) and then tells King he doesn't remember what happened, and later (after seeing CNN clips) says he does remember what happened but he misspoke. He also refers to the events of that evening as "a blur." So I'm not sure what we should expect to "learn" here, but if you like trainwrecks...

America's Got Talent (9pm, NBC) - Speaking of train wrecks, David Hasselhoff will be performing on tonight's show. He will be singing (and hopefuly dancing!) a song called "Feeling Good."

Glee (9pm, Fox) - Fox is wisely repeating the pilot for
this very nice musical-comedy-drama about a high school glee club from the creator of "Nip/Tuck" and "Popular." You can also watch online. The official premiere is September 9.
