"After the first show this evening, I had a massive heart attack," the "Clerks" director, writer and actor tweeted early Monday. "The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka 'the Widow-Maker'). If I hadn't canceled show 2 to go to the hospital, I would've died tonight. But for now, I'm still above ground!"

Actor Chris Pratt was among those who flocked to social media to wish him well.

According to the New York Daily News, Smith, 47, taped a stand-up performance Sunday evening in Glendale, California, but canceled a second taping scheduled for 9 p.m.

"Kevin we don't know each other too good but I have loved you since Clerks and I'm praying my [expletive] off for you cause I believe in the healing power of prayer," Pratt tweeted. "Can you please pray with me people!?"
