The girls were taking part in a prank when the unsuspecting girl in the video made the comment
Kendall and Kylie Jenner may have been in on a prank, but they were the ones who were left shocked when the unsuspecting women they were playing the prank on, called the Kardashians "slutty".
In a clip of Howie Mandel's prank show called Deal With It, the Jenner sisters can be seen feeding words to the guy who was sitting with the unsuspecting woman in the hidden camera prank. But as the guy says she is "crazy like the Kardashians", the woman responds with: "No, I'm not slutty."

The clip then shows the woman getting embarrassed as she spots Kendall and Kylie coming towards them.

"Gotta keep sister close."
