Scott Disick arrived at Los Angeles International Airport for a flight to London on Friday, and as usual, the father of three maintained his very best poker face and breezed right into the terminal. We're not sure what LD is doing in London, but we have a feeling it's for an appearance. The only question is, why isn't his young, hot girlfriend, Megan Blake Irwin, with him?

Scott has been dating the blonde model for a few weeks now, and after being glued at the hip in Vegas and Los Angeles, we're wondering if that's already fizzled out. You see, the other day, Scott posted a meme on Instagram of infamous horror movie serial killers Jason Voorhees (Friday The 13th) and Michael Myers (John Carpenter's Halloween) in bed together, with the caption, "When you're in a relationship and you're both crazy." Um. What?! Is he talking about Megan or baby mama Kourtney Kardashian?!
