Clearly unfazed by the flying kick, Schwarzenegger assured fans he has not been hurt.
"Thanks for your concerns, but there is nothing to worry about," he tweeted. "I thought I was just jostled by the crowd, which happens a lot. I only realized I was kicked when I saw the video like all of you. I'm just glad the idiot didn't interrupt my Snapchat."
