While Kourtney wouldn't confirm her sister's rumored romance with the heartthrob, Khloe told ET that the two
are an item. "I don't know if they're like boyfriend-girlfriend," Khloe explained. "Nowadays I don't know. People are weird with stuff. So, I don't know their title. But I mean, they were in St. Barts together hanging out, so to me that's dating."
