Kim Kardashian claims that sister Kourtney and her beau Scott Disick are "better than ever".

Kourtney shares two young children with partner Scott son Mason, two, and daughter Penelope, two-months.

In Touch magazine reported that the 33-year-old reality star Kourtney is absolutely fed up with Scott's partying ways and is ready to leave the relationship.

Kim claims that rumours about Kourtney and Scott going through a rough patch are absolutely untrue.

"They are better than ever," Kim told Us Weekly.

Kim thinks Scott is a great guy.

She claims that the couple have much more important things to think about than to address silly rumours.

"I feel bad Scott gets such a bad rap," she said.

"Good thing they're too busy being parents to pay attention to nonsense!"

Apparently Kourtney and sibling Khlo are preparing to move to Florida for a little while to film their reality show Kourtney & Kim Take Miami.

"They leave next week," Kim confirmed.
