GOSSIP: Khloe & Kourtney Kardashian: Jet-Setting Sisters

They're always up to something, and Kourtney and Khloe Kardashian were spotted arriving for an outbound flight at JFK Airport in New York City on Wednesday (June 8).

The “Keeping Up With the Kardashians” sisters shared a laugh as they made their way through the terminal with Kourt’s baby daddy, Scott Disick, and son, Mason, not too far behind.

Yesterday, the sisters made a promotional appearance on Fox & Friends, and Khloe had a bit of a “slip-up” thanks to wearing a sheer top without sporting any undergarments underneath.

After the show, Khloe tweeted, "My mom just called me saying my nip slip is 'all over the internet! Ha! Is it weird that I love it?! Who knew nipples were so special?"
