Kristen's Mini Coop Mixup

It’s one of those embarrassing little moments that make you want to runaway, even if you’re the star of The Runaways -- and has the pics of Kristen Stewart’s Mini-Cooper mix-up.

The Twilight beauty was house hunting in Beverly Hills on Tuesday when she walked up to a car with keys in hand, got inside, before suddenly realizing -- it wasn’t her car!

Hey, it could happen to anyone! After all, the Mini Cooper was the exact same make and color as hers.

But our favorite part of the story is that the Mini Cooper actually belonged to a paparazzi who was following her!

Stewart had a quick laugh at her own gaffe and found her actual vehicle -- call it the Bella-mobile.
