According to People magazine, Kelsey Grammer is in a Hawaiian hospital after suffering a mild heart attack. A rep for Grammer says it happened Saturday morning as he was paddle boarding with his wife near their home in Hawaii. He immediately went to the hospital where doctors determined it was a mild heart attack. He'll be in the hospital for a few days for observation.

Grammer was most likely enjoying a little time off before he returns to television this fall. His Fox sitcom, Back to You, was recently canceled but he quickly rebounded and took a role on an ABC comedy called Roman's Empire. He'll have the title role, actually, as Roman, the wacky patriarch of a wealthy and eclectic family. This new comedy is a departure, of sorts, for Grammer. Rather than the Frasier and Back to You-style sitcoms with multiple cameras, his new project is a single-camera venture.
