Kelsey Grammer recently revealed to the New York Post the reason why he had a 30-year falling out with “Cheers” co-star Ted Danson. The two actors appeared on a podcast last October where Danson apologized to Grammer for an incident on the “Cheers” set that resulted in them not speaking for three decades.

"It was at a time in my life when I was actually going through a lot of self-doubt, self-loathing, honestly," Grammer said. "It was when I was drinking a lot."
