VIDEO: Kourtney Kardashian Tries to Hide a Hickey in New 'KUWTK' Teaser

Much of the hilarity (and oftentimes snarkiness) created by the Kardashian sisters comes from the fact that they are all up in each other’s business. So much so that it kind of seems like they forget at times that they are all grown a*s women who can do whatever they want.

Which is why fans are cracking up over this one of this week’s Keeping Up With the Kardashians clips. In the video below, 40-year-old Kourtney saunters into the kitchen where her sisters, Kim and Khloé, are having a conversation. But from what happens next, you would think Kourtney is actually 16 and her sisters are actually her irate mothers.

The Poosh founder is subtly trying to hide a fresh hickey on her neck, but it lasts all of about one second before both Kim and Khloé begin interrogating her. After badgering her about “Who on earth would give her a hickey?,” the mom-of-three finally states, “Just let me live my life!”

Later in her confessional, Kourtney expresses her annoyance at her meddlesome siblings, saying:

“My sisters are pretty nosy when it comes to anything in my life. I don’t know if they’re bored in their own lives and they want to live through my wild dating life that they think is going on. Like, come on, guys. Let’s get it together.”

As much as we would love to know who has been nibbling on Kourtney’s neck, she does have a point.
