Turns out, Paris wasn't AS terrified as we thought. According to TMZ, she was actually in on the whole thing. The site obtained documents sent from the Egyptian production company responsible for the prank, which they apparently sent to a bunch of American celebrities offering them a lot of money to participate.
"We will act as if something is going wrong and ask all passengers to jump off the plane!!! Of course everyone will panic, we'll be having skydivers in disguise with us on board," the document states. "We will monitor the funny reactions from our celebrity guest when they fear jumping off the plane."
So, the good news is that Paris didn't get pranked into believing she was about to die in a plane crash. In fact, the joke is on us, because WE got pranked into believing that Paris got pranked.
