David Letterman

‘The Colbert Report’ has already said its goodbyes, while David Letterman will hang onto the ‘Late Show’ until May, so when does Stephen Colbert finally take the desk, and begin our new era of ‘Late Show with Stephen Colbert?’ Find out, as CBS has released the official start date, and teased some specials from Letterman himself!

Actress-singer Anna Kendrick is somewhat notorious for making filthy (hilarious) jokes on Twitter and is overall really charming. Her most recent appearance Tuesday night on CBS' "Late Show with David Letterman" only continued to make that the truth.

Stephen Colbert has already begun making the final rounds of ‘The Colbert Report’ in preparation for his new CBS ‘Late Show’ hosting gig, but don’t expect David Letterman to vacate the chair just yet. The longest-running late-night host has officially set a departure date for May 2015, bringing an end to ‘The Late Show with David Letterman’ as we know it.

Often, particularly colorful characters take to the various late shows to flex the full range of their unique spirit, just for funsies. Joaquin Phoenix looked to be going down that precise path on last night's 'Late Show,' actively imitating himself learning yoga, calling his more personal bits "Julio Igelasias," and just generally having a good time. Host David Letterman looked nervous, but Phoenix looked relaxed, and that might be why Phoenix's good-time appearance took a serious turn when the 'Inherent Vice' star announced his engagement on air.

Here is a brief list of things that happened during Jennifer Lawrence's appearance on 'The Late Show' last night: she sang with host David Letterman, the duo discussed tummy troubles, they chatted about bowling, they both totally biffed introducing a clip, Lawrence begged Letterman to not retire, they walked out during a live taping, and then Lawrence took over the entire show.

Although we understand that 'The Late Show' will be getting a bit of a makeover when long-time host David Letterman exits later this year, and while we're extremely excited that Stephen Colbert is taking over the post, we still have a teensy idea: maybe Bill Murray could host it? Or just appear on every single episode? Does Colbert need a sidekick? He has to, right?

When you've been in Hollywood as long as Michael Keaton has, you've probably seen a lot of weird stuff created by fans -- a lot of signs and strange drawings and maybe a wacky letter here and there -- and although that sounds a little off-putting, Keaton is into it. At least, he's into it when your fan art is good, as was the case with a 'Beetlejuice' tattoo he spotted during a late night shoot on his upcoming 'Birdman.'

"Summertime! Summertime, people!" Sure, Bruce Willis. We can blame this on it being the summertime. The actor hit 'The Late Show' last night to ... honestly, we don't even know, but eventually it devolved into Willis eating corn on the cob harmonica-style and getting absolutely covered in melted butter. It seems that Willis is a huge fan of corn -- can't get enough of it! -- and he was eager to share some corn-centric life hacks with host David Letterman.

From 2003 to 2006, Dave Chappelle's show on Comedy Central was an absolute hit. It was a sketch comedy show featuring Chappelle, as well as many other comedians and guest stars. Then, while shooting the third season, Chappelle abruptly left the show and pretty much disappeared from the public eye.

James Franco is, to put it diplomatically, a bit of an odd duck. Sure, he's a very talented guy -- and one who has never balked at using his talents across a wide range of professions -- but he's also kind of a weirdo in plenty of situations, especially as they apply to social media. And David Letterman is not having it.
