Kardashian Kids: The Next Jenneration

Kourtney loosens up her buttons and it's all kinds of cringe-worthy.

Kourtney Kardashian found a great way to embarrass herself and Kim Kardashian at the same time: a flash mob. Yes, apparently people are still doing these in 2018.

In a preview clip from this Sunday's "Keeping Up with the Kardashians," Kourtney gets revenge on her sister for ruining her dance class "with her critiques" by surprising her in public with a group performance to The Pussycat Dolls' "Buttons."

After enlisting Khloe Kardashian's help to get Kim to an outdoor mall, Kourtney and her backup dancers started to do their thing in the middle of the promenade.

Kim reacted with shock, before exclaiming, "I'm literally going to cry ... what the f--k is going on?!"

Khloe even momentarily joined the fun, before quitting as she said, "I'm too pregnant to do this."

In a confessional, Kourt explained it was all part of her plan to embarrass her sister. "Did I succeed?" she asked. "You did," Kim responded.

Mission accomplished.
