(CNN)--Comedian Gallagher, famous for smashing watermelons, is in a Texas hospital after suffering a heart attack, according to the celebrity-watching website T-M-Z.
He was preparing to go on stage at a Texas club Wednesday night, when he started to feel chest pain.
Gallagher's manager tells T-M-Z the heart attack was "mild to serious" and the 65-year-old will remain in the hospital for the next couple of days.
This isn't Gallagher's first heart scare.
He suffered a minor heart attack while on stage last year.
One year after a deadly shooting rampage in Marathon County, the community and businesses honored the four lives lost in different ways.
