Kelsey Grammer

Of all the stars on television, no one can play the same character for 20 years quite like Kelsey Grammer.  The U.S. Virgin Islands native was to play the well-read Dr. Frasier Crane for only six episodes on Cheers, but the character took off and got his own spinoff (Frasier) when the show ended.  A stint at the Betty Ford Center was just what the doctor ordered after Grammer flipped his Dodge Viper while intoxicated in 1996.  Grammer kept a low tabloid profile until his marriage to Playboy model Camille Donatacci unraveled in a spectacularly bitter fashion in 2010.
