In a sneak peek clip from an all-new episode of Keeping Up With the Kardashians, Scott Disick gets into an argument with his ex-partner Kourtney Kardashian, after he learns he wasn't invited to Khloe Kardashian's birthday bash.
"F**k, I didn't even get invited to her birthday," Disick says during a heated conversation with Kourtney and Kim Kardashian West. "And I'm family. That was really sweet. That made me feel really good."
So, what was the reason?
"I didn't want to have you coming to the birthday and be photographed going in," Kourtney says, later admitting that's not what she "really" meant. "I'm a little bit caught off guard. I was trying to be positive. I didn't want to say I just didn't want you there."
"That's all bulls**t," he replied. "It's funny to realise just how fake you really are though."
