What's wrong, Kimmy K?

Kim Kardashian teared up as she tried to make it through traffic in Beverly Hills yesterday, and while we don't think the reality star is sensitive enough to lose her cool over a few extra minutes in the car, we're wondering if there was something else that was bothering her?

The Keeping Up with the Kardashians star looked a little puffy and swollen and wasn't wearing her usual face full of makeup, so it's possible she had an allergic reaction to her cosmetics, because she was rubbing her eyes pretty excessively. Also, when we spotted her yesterday her lips were noticeably more plump, so she could have had a bad reaction to a cosmetic procedure. Either that, or the brunette beauty and husband Kanye West are actually fighting like it has been reported.

We are dying to know what the problem was!
