'Dancing With The Stars' Season 24 Premiere - ArrivalsOlympian and "Dancing with the Stars" contestant Simone Biles is the latest celebrity to fall victim to one of Ellen DeGeneres's sneaky pranks.

The gymnast got quite the scare while sitting down for a recent interview on "The Ellen DeGeneres Show." Although the talk show host warned Biles that her "DWTS" partner, Sasha Farber, is a "prankster," the gold medalist was completely caught unawares. This worked out well for viewers, because it made for a priceless reaction when Farber did finally pull a prank on his co-star.

The professional dancer and DeGeneres get a 10 for their work. As simple as their prank was, they executed it executed perfectly and were rewarded with a terrified shriek any practical joker would hope for.

Watch Biles's appearance on "Ellen" below, and keep an eye out for the flawless prank around 3:50.

If you want more of Biles and Farber, you can catch them on "Dancing With the Stars" on Mondays at 8 p.m. ET/PT on ABC.
