After the duo met up last year to figure out how they could collaborate on a prank to trick her friends, it never came to fruition because of their "busy schedules," he wrote on the YouTube page for the prank. "A long time after, I revisited the idea with my team, this time with a twist. I WANTED TO PRANK SHAY. After months and months of planning and scheduling with her team, we were finally able to make it happen."
To do it, Yousef sat through four hours of make-up to transform into a creepy looking, elderly driver. Next, he took the Pretty Little Liars star on the ride of her life that left her in tears before it was revealed that she had been pranked.
That's about as much as we can say without spoiling the hilarious prank for you. Watch the video above to see what went down!
