Kim Kardashian's Prenup -- Kris Humphries Comes Up Goose Eggs in Divorce

Kim Kardashian will not pay Kris Humphries a red cent in their divorce ... TMZ has learned.

As we first reported, Kim and Kris have a prenup -- which Kim felt was "the smart thing to do."

Now that leaves just one piece of business on the table -- Kim's $2 million engagement ring. Sorry Kris, but you lose on 2 counts:

1. Under California law, once you said "I do," you lost any rights to the ring
2. You didn't pay for the ring, stupid
