Britney got a flat tire in Beverly Hills today, which is not uncommon considering the generally lousy condition of many streets here now.

A phone call later, she then tries to make a getaway, but doesn't get very far!

Instead of changing her flat tire (the paps even offer to change it for her!) ... she ditches her car and jumps into a pap's car....... Fabrezio from agency X17!

My oh my Brit -- you are getting familiar with your Pap Boys!
