Khloe Kardashian -- The Single Life Is Work (PHOTO)

Screw the horse ... freshly single Khloe Kardashian's getting right back on the cow -- the cash cow that is her family's reality show.

Days after finally putting her Jane Hancock on docs to divorce Lamar Odom, Khloe reported for work decked out in virginal white. She was shooting a 'KUWTK' scene with Kris Jenner and sis Kourtney at a restaurant near their Calabasas homes.

Not that KK is living off Lamar's dough, anyway -- but good to know ... she's gonna make it after all!!
