Kourtney Kardashian, Scott Disick Burbank airport Las Vegas

Did Kourtney Kardashian and Scott Disick have a lovers' spat?

The couple looked upset with one another, keeping a huge distance between themselves, as they walked though Burbank Airport on Saturday. The duo had just returned form Las Vegas so Scott might have reverted to his old partying ways.

As captured on several episodes of Keeping Up With the Kardashians, Scott usually drinks too much in Sin City then fights with his longtime girlfriend. Or he shoves money in waiters' mouths.

Then again, maybe Kourt was still recovering from being confetti bombed the day before. Unexpected colorful confetti showers can be traumatizing.

Whatever the issue, we hope these two work through it soon.
