Sibling jealousy! Khloe Kardashian has addressed fake reports that Scott Disick and Kendall Jenner are having an affair via a very funny Twitter exchange with the man himself.

The story in question is Star magazine’s latest cover which claims new mom Kourtney is devastated after discovering her sister Kendall is secretly dating her husband. But taking the story a step further, Khloe decided to throw her own bit of outrage into the mix by posting an amusing tweet about Disick.

"I'm really pissed about this whole @KendallJenner and @ScottDisick thing!!" she wrote on Wednesday, Jan. 29. "Scott, I thought it was you and I that was having the affair!"

"Scott is such a THOT!" she added. "These hoes really ain't loyal!! Huh?!?! Damn Gina!!! Damn!!!"

Quick to respond, Disick tweeted back to his sister-in-law. "Don't worry @khloekardashian, You will always be my number 1," he wrote.

Retweeting his reply, Khloe added, "That's what's up Lord!!!"

It's not the first time Khloe has called out magazines for inventing stories about her and her family's love lives. In November of last year she tweeted a photo of Life & Style's front cover, claiming she was in a secret relationship with Disick.

"These mags are like a great telenovela," she captioned the snap.
