Back from paradise! And now it's time for Kourtney Kardashian to face questions about baby daddy Scott Disick's tryst with 19-year-old Bella Thorne. While Kourt was sharing a stateroom with male model boyfriend Younes Bendjima on a yacht with half-sis Kendall Jenner, Scott decided to take his teenage f-buddy to the South of France. As soon as he sobered up slightly, he realized he had made a massive mistake and kicked her to the curb ... or back to the Nice airport, as it were, and traded up for last-summer's POA Chloe Bartoli.

As the two put on a sexy display for photographers, making out in the pool of Scott's luxury villa, ass-grabbing for the cameras, pathetic Bella was Tweeting, "Yo this #cannes fancy life isn't for me." Uh, yeah -- it's not for you because you got dumped and didn't have a choice. And because teens with septum rings and zits don't play well with the chic Cannes crowd -- you're not going to Gotha with rainbow hair, darling.

So back to Kourt -- she, with her shiny travel skin -- didn't feel like talking about Scott's vacay hookups, plural; she simply made her way to the car with a smirk on her face. Kendall, meanwhile, looked like she was ready for Aspen -- apparently she forgot that, while LA isn't the French Riviera, it's not glacial! Why all bundled up, KJ?
