Kim Kardashian's Assistant Drives Car Into Mailbox -- That's How She Rolls...

Kim Kardashian got something special in her mail box over the weekend ... clumps of paint from her $300,000 Rolls Royce.

Seems Kim's assistant isn't proficient at navigating the ostentatious whip ... she tried backing out of the driveway and tore into the mailbox. What's amazing ... she didn't stop when she heard metal-on-metal.

Kim is all too forgiving ... her assistant's job is secure and the repair costs -- which could approach $20K -- will not be deducted from her salary.

Someone should bookmark this post for North West ... it's called precedent.
