TV vet Kelsey Grammer suffered a mild heart attack on Saturday, and is now resting comfortably in a Hawaiian hospital.

Grammer, 53, is expected to be released early this week.

"Grammer experienced symptoms Saturday morning after paddle-boarding with his wife Camille at their Hawaiian home," reads a statement from Grammer's rep. "He was immediately taken to an area hospital where it was determined that he had a mild heart attack."

Stan Rosenfield, Grammer's agent, said his involvement in the prospective ABC series Roman's Empire will not be affected as the pilot has already been taped. - MWM
