Kourtney Kardashian Left Raging After Scott Disick Invites Girl On Family Holiday

While Kourtney Kardashian and ex Scott Disick seemed to have the co-parenting thing down to a tee, they've hit a bump in the road in the form of Scott Disick inviting a girl on their family holiday to Costa Rica.

In the latest episode of KUWTK, Kim's assistant Stephanie Sheppard stumbled upon the fact that Scott had invited someone called Chelsea to join him on the holiday, who then told Kim, who in turn told Kourt.

"Scott and I are living our open lives but we’re here with our kids and here to be a family so I can’t even understand why he would think to invite someone. It’s hurtful and disresepectul," she fumed.

Responding to Kris asking if she's handling the news well, Kourt said: "Yeah, I’m just thinking about all the guys I’m going to f**k when I get home!" 

"My kids deserve to have somebody with better moral characteristics," she later told Khloe. "I’ve already had the epiphany - this is just confirmation."

As for how the rest of the Kardashians took the revelation, the episode ends with Kim chucking a glass of water on Scott before he gets the chance to actually explain what was going on.

Yikes. In better news, here's everything you need to see from the MTV Movie & TV Awards...
