Kim Kardashian just snapped up a brand new $150K 2013 Mercedes G63 and posted this pic to Twitter to make all her followers green with envy, and the pricey ride apparently isn't even available yet, with the 31-year-old bragging that she "got the first one!"

The luxury car is the latest addition to the Keeping Up with the Kardashian star's extensive collection, which includes a Bentley, Ferrari, Range Rover, and two Rolls Royce. Let's not forget the outrageously expensive Lamborghini she bought for boyfriend Kanye West's birthday either!

Countless photo shoots, spinoff shows, and endorsement deals have brought in the big bucks for the brunette bombshell, and she took some time to reminisce about some of her favorite projects on her official website the other day.

Posting this vintage snapshot, Kimmy wrote,"This was a shoot I did in Mexico a few years ago! Troy Jensen did my hair, make up and photography. We had so much fun! I loved the cowgirl theme of the shoot!"

With that body, it's easy to see where all Miss Kardashian's cash is coming from!
