VIDEO: Khloe Kardashian, Lamar Odom Keeping Mum On Marriage

Soon-to-be husband and wife Khloe Kardashian and Lamar Odom stayed mum when pressed for details about their upcoming wedding as the couple was attending an anti-puppy mill benefit in Hollywood Hills on Tuesday night.

Kardashian, as RadarOnline.com predicted earlier, sported some "ginormous" jewelry.

Sources close to Kardashian say that 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. The reality TV diva is not pregnant, but deeply in love, a source said, while Odom "got to that point in life where he wanted to settle down then she came into his life not long after."

Their wedding ceremony will take place Sunday at the palatial Bel Air estate of music mogul Irving Azoff. Notable names on the guest list include Ryan Seacrest, all the Kardashian relatives (Kim, Kourtney, Brody Jenner) and Odom's Laker colleagues (Kobe Bryant has yet to RSVP).
