Rachel Uchitel Milks Another Tiger

Rachel Uchitel has finally met a tiger she can't squeeze $10 million out of ... and TMZ has obtained the footage of the exotic encounter. 

Tiger Woods' mistress numero uno recently shot a series of Facebook videos for Cameo Stars -- a la Lindsay Lohan -- in which she canoodles with an adorable (and equally deadly) tiger cub.

During the shoot for the video messages -- which are launching this fall -- Rachel handles the growling, hungry tiger like a pro ... and at one point feeds it milk out of a baby bottle like she's got a B.S. in zoology.
