Only Jimmy doesn't know about it.
With the help of Kimmel's wife, Molly, Rihanna pulled off a pretty hilarious prank on the king of pranks himself.
As an April Fools' Day joke, Rihanna, her dancers and entourage, armed with confetti, glow sticks, strobe lights and enough dollar bills to make it rain on the sleeping and unsuspecting late-night TV host, snuck into his room and started to party on down.
In the video, a stunned, confused and bewildered Kimmel takes a few moments before he realizes what it going on when Rihanna busts into her latest hit, "Bitch Better Have My Money," while jumping on his bed and flashing lights in his eyes.
Rihanna has before mentioned how she likes pulling pranks and that her band suffers the most. She also said if she was going to be on Jimmy Kimmel Live! on April Fools' Day, she had to prank Kimmel himself!
