Kardashian is sporting some "ginormous" jewelry, our source said, and is expected to show it off Tuesday; a prenuptial agreement has been discussed, but not yet confirmed, as the NBA vet's recent contract with the Lakers pays him $33 million over four years.

It's been a whirlwind of a romance, the two met on August 27th at the Ron Artest party at Halo in Hollywood and instantly hit it off. Khloe's sister Kim has gushed about how happy they are together.
