No watermelons were smashed with giant sledgehammers last night...because Gallagher suffered a heart attack before he was supposed to go onstage at a bar in Lewisville, Texas.
There's a restaurant in Las Vegas called the Heart Attack Grill that prides itself on serving some of the world's least healthy burgers. And on Saturday, a man in his 40s was eating there and had an ACTUAL HEART ATTACK. Other customers thought it was a publicity stunt, and were taking photos of the guy.
