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

After Stephen Colbert announced "The Late Show" was being canceled by CBS, fellow late-night hosts Jon Stewart, John Oliver, Jimmy Fallon, Seth Meyers, plus other hosts and comedians, showed up to support him.

Monday night's (July 21) show also featured kiss cam-style pop-ins from supportive fellow talkers Anderson Cooper, Jimmy Fallon, Jon Stewart and Adam Sandler.

After CBS said it was canceling "The Late Show," people online claimed its host announced a new show in collaboration with MSNBC host Rachel Maddow.
