Not cool. Everybody likes a good celebrity prank, but one Egyptian TV show took the trickery too far while scaring Paris Hilton. In the newly released clip, the heiress and TV star, 34, is on board a small plane with a group of people when she starts to smell something unpleasant. 

Suddenly alarms go off and the plane begins to nosedive as a screaming Hilton cries. 

"Is this normal?" she loudly asks. "What is happening?!" 

Then a man lifts up a door on the side of the plane, grabs a passenger and jumps out the side of the plane. 

Hilton screams, "I don't wanna jump! I'm not jumping!" 

The plane eventually lands as Hilton continues wailing and crying along with the rest of the passengers. She's escorted outside where she is comforted by the man who had been sitting next to her throughout the flight.

"I'm so sorry. I'm a bad guy, I'm a naughty," the man said. "I am an Egyptian actor. This is a prank show!" 

Once the video went live, Hilton tweeted, "Scariest moment of my life. I really believed the plane was going to crash & we were all going to die." 

Watch the terrifying clip now.
