Kendall Jenner calls her mother Kris Jenner a 'whore' on 'KUWTK'

LOS ANGELES, June 23 (UPI) -- Kendall Jenner surprised viewers during Sunday's episode of Keeping Up With The Kardashians by verbally abusing her mother, Kris Jenner.

The incident, in which Kendall's sister Khloe Kardashian also dissed her mother, took place at a spinning class the sisters attended along with Jenner and Kim Kardashian.

During the class Kendall told an enthusiastic Kris that it was "so annoying" that she always wanted to be the center of attention.

"Eww mom, you're so embarrassing, you need to act your age," she said later, eventually adding that she was a "desperate [expletive] whore."

While the even-tempered Jenner failed to address any of Kendall's claims, a clip of the incident shows that she was clearly bothered with her daughter's comments as was Kim. Khloe, on the other hand, laughed at most of Kendall's comments and is later showed in a voice over saying that her mother has been needing a lot of attention since her separation from Bruce Jenner.

Later in the episode, Kendall made peace with her mother by giving her a big hug and promising to take better care of her dog, an issue that the two dealt with earlier.
