Kim, Khloe upset over Scott Disick's new girlfriend

Reality TV stars Kim Kardashian and her younger sister Khloe Kardashian are reportedly disappointed with the relationship of their elder sister Kourtney Kardashian's former partner Scott Disick with another girl named Lina Sandberg.

"Khloe and Kim know about it and are pi**ed off because they are overprotective of Kourtney," eonline.com quoted a source as saying.

"None of them are taking it very seriously because it's just another random girl that Scott is seen running around with.

"He's made it apparent that he's still not over Kourtney and would drop any chick if Kourtney decided to take him back," the source added.
