David Letterman is subtly showing support for his successor Stephen Colbert after CBS' shock cancellation of "The Late Show."

Late-night rivals and other celebrities rallied to support CBS "Late Show" host Stephen Colbert after the network canceled his show, and comedian Jon Stewart lashed out at Paramount Global for the decision to end the long-running TV program.

Sandra Oh criticized CBS and Paramount during her appearance on 'The Late Show with Stephen Colbert' on July 21 after its cancellation was announced. The network said it was "a financial decision," but the news came days after Colbert criticized Paramount for its $16 million settlement with President Donald Trump.

Late-night host Stephen Colbert had a vulgar retort to President Donald Trump taunting him over his cancellation, saying "go f--- yourself" to audience cheers.

John Oliver, Jon Stewart, Jimmy Fallon, Seth Meyers and more had cameos during the July 21 episode of "The Late Show With Stephen Colbert."

The late-night host acknowledged that "a lot of people out there are bummed" about the show ending next May, so he tapped a few famous friends to cheer everyone up.

Fox News host Greg Gutfeld is the ratings king of late night with 3.1 million average viewers, despite what Stephen Colbert may be telling his audience.

For one night only, Bad Bunny will appear as a guest on 'The Late Show With Stephen Colbert,' followed by 'Late Night With Seth Meyers'
