Lisa Vanderpump -- My Little Little Ponies Fly Private (PHOTOS)

EXCLUSIVE

Lisa Vanderpump just bought the farm ... or a good chunk of one, anyway -- she's added 2 miniature horses to her backyard petting zoo, and they arrived by private jet ... naturally. 

The mini livestock flew in Monday on a customized plane -- 2 seats had to be removed to make it more of a flying barn ... unlimited hay included.

The ponies normally cost $3,500 a pop, but NEIGH -- we're told Lisa got a 2-for-1 deal!

We're told the ponies -- birthday gifts for Ken -- will live in Lisa's yard (new cast members alert!) and share the land with her 2 swans and multiple dogs.  

Unlike most Bev Hills brats, LV wants to put these girls to work as therapy ponies at hospitals. They're still nameless for now, but we're told Lisa's friends will get a say. 

Brandi is a nice name, no?
