It’s stressful being a celebrity—sometimes you just have to sweat it out to let it out. And other times, you’ve got to sweat it out because…that’s what it says in the script. (That’s showbiz). So when these icons weren’t busy jet-setting around the globe or hanging out by the pool for a day, you could find them on the nearest field, court, course, or ring, either getting in a workout, or making it look like they were getting in a workout. From getting 18 holes in on the course to hitting the slopes (and surely a little apres ski), these vintage photos of celebrities playing sports prove that old Hollywood stars knew how to play ball.
