"No one loves a prank more than me; I don't find cruel pranks entertaining at all," Kathy exclusively tells ET.
The YouTube video of the prank -- shot for Ramez Galal's show Ramez In Control -- surfaced on Saturday, showing Paris going on what she thought was a 15-minute tour of Dubai.
During the flight, the plane takes a nosedive, sending the passengers -- all in on the joke except Paris, some even skydiving out of the plane -- into hysterics. When the plane lands safely, Paris is visibly shaken and concerned about the other passengers. After she realizes it was all fake, Paris reveals that flying is her biggest fear.
"I almost thought I was going to die," Paris said. "That's been my biggest fear my whole life -- dying in a plane. I fly almost every day of my life ... I've never had turbulence like that in my life. I thought we were going to land in the water, and I thought we were going to get thrown off the plane. I'm shaking."
