If you keep up with the Kardashians at all, you may know that the rumor du jour is that Scott Disick is cheating on Kourtney Kardashian with her 19-year-old half-sister Kendall Jenner. Or at least that’s the cover story Star magazine has come up with this week.

In response to the magazine’s claims, Khloe Kardashian decided to have some fun on Twitter Wednesday:

I’m really pissed about this whole @KendallJenner and @ScottDisick thing!! Scott, I thought it was you and I that was having the affair!

— Khloé (@khloekardashian) January 29, 2015

Scott is such a THOT! These hoes really ain’t loyal!! Huh?!?! Damn Gina!!! Damn!!!

Disick was quick to respond to Khloe’s tweet, writing, “Don’t worry @khloekardashian, You will always be my number 1.”

Kendall, who was also clearly amused by claims of the affair, chimed in by pretending to be upset over Disick’s tweet to her sister.

excuse me?! RT @ScottDisick: Don’t worry @khloekardashian you will always be my number 1

— Kendall Jenner (@KendallJenner) January 29, 2015

Of course, Khloe had the best response:

He wants an LA face w/an Oakland booty! “@KendallJenner: excuse me?! RT @ScottDisick: Don’t worry Khlo, you will always be my number 1”

— Khloé (@khloekardashian) January 29, 2015

It’s clear that at this point the family is used to far-fetched claims from tabloids, but it’s not even the first time Disick has been accused of stepping out on Kourtney with one of her sisters.

In November, Life & Style magazine claimed that Disick was in love with Khloe, who responded to the rumor by posting a photo of the magazine’s cover and writing, “These mags are like a great telenovela.”
