Late Night Hosts Pay Tribute To Joan Rivers: She Had Guts, Never Stopped Working & Made No Apologies

It was an emotional night for late night hosts, as they all took time on their shows to pay tribute to Joan Rivers, who died on Thursday at the age of 81.

Jimmy Fallon's voice began to crack as he recalled having Rivers on his first episode of "The Tonight Show," and David Letterman praised the controversial comedian for making no apologies. "Talk about guts," he said, more than once.

Take a look at how all the late night hosts responded to the sad news:
