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.

Kelsey Grammer has opened up about his messy decades-long feud with his Cheers co-star Ted Danson that saw the pair not speak 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."
