Khloe Kardashian Is ''Worried'' About Scott Disick's Behavior While Kourtney & Kids Are Out of Town: Find Out Why!

Khloe Kardashian is concerned about Scott Disick.

When Keeping Up With the Kardashians returns this Sunday, Kourtney Kardashian leaves town for a month with her and Scott's kids...without Scott. Since Scott is left in L.A. by himself, he has a lot of down time and admits that he's "anxious."

In this clip from the episode, Scott talks to Khloe about being away from Kourtney and their kids.

"You know this is gonna be like the longest I'm away from Kourt and the kids...ever," Scott tells Khloe.

"How do you feel?" Khloe asks.

E!

Scott admits that he's "kinda anxious" and says he wants to "book" his time and possibly do some appearances so he doesn't "think about missing the kids and Kourtney."

"But are you gonna be on your best behavior?" Khloe asks.

"Worst!" Scott jokes.

Khloe then tells Scott, "Just make sure you're doing whatever you think is best."

Take a look at the clip above to see Khloe explain why she's "worried" about Scott!
