Earlier this week, in her latest jet-setting adventure, heiress Paris Hilton was pranked into thinking the private she was on was going to crash… but now it's been reported she was in on the whole thing.

Anyone who's watched the video, made as part of an Egyptian TV prank show, will have seen Paris screaming in what looked like genuine fear for her life as the small plane plunged toward the water below. Paris herself tweeted after the event saying "Scariest moment of my life. I really believed the plane was going to crash & we were all going to die. "

The internet went absolutely crazy after the video was first released over the weekend, with many people feeling like the TV prank show might have gone too far with the "joke." 

Yesterday it was reported that Paris herself agreed that the prank was a bit too extreme and that her lawyers insisted she had a very strong case to sue the Egyptian TV show Ramez in Control for emotional trauma.

But alas, it turns out that Paris is a way better actress than we gave her credit for, as TMZ are reporting she knew all about what was going to go down when she got aboard. The gossip site claim they have gotten hold of contract drawn up by the show's producers before the prank was recorded, and the story it tells is very different to what Paris has been putting out there all week.

According to TMZ, the Egyptian company approached other celebrities first as Paris wasn't their first choice. The company sent an offer of a huge payment to several other American celebs but everyone declined except for hotel heiress Paris.

The contract reportedly states: "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." It then goes on to say "We will monitor the funny reactions from our celebrity guest when they fear jumping off the plane."

Speaking to reporters earlier this week, Paris said she felt the TV show took things "too far"… but to be fair, she's the one that agreed to get on board the plane for a fake crash.
