Kourtney Kardashian's focus is entirely on her children.
In a clip from this week'sKeeping Up With the Kardashians, the reality star discusses her ex, Scott Disick, who recently checked into rehab. The two split over the Fourth of July weekend when Scott was photographed with a former flame, and judging by her demeanor, the 36-year-old is exhausted ay all the drama.
"I don't know," says Kourtney, when asked if Scott is OK. "I mean, this is what he wants to be doing, so there's nothing I can do at this point. That's life."
