Kourtney Kardasian and Scott Disick took their oldest children, Mason and Penelope, to the movies on Sunday in Calabasas, and if we didn't know any better, we'd swear that they're back together!

Er, wait a minute. According to reports, they ARE back together! For now, anyway. After going on a romantic getaway to Miami, the duo are apparently giving things another shot. "Kourtney thinks that this vacation was exactly what they needed to get them back on the right track," a Kardashian source told Radar. "Kourtney thinks that Scott needed to be shut out of her life for him to realize how much she means to him."

Apparently they've been hooking up for months, and they "had a lot of sex" in Miami. Well, just because they're banging doesn't mean they're officially back on, but seeing as they have three kids together, it wouldn't be silly to say they've reconciled. Or would it?
