Kim Kardashian -- Mrs. West Returns

With husband Kanye West nowhere in sight, Kim Kardashian returned to the U.S. Sunday following the couple's multi-country wedding/honeymoon extravaganza.

KK signed a few autographs as she made her way through LAX ... accompanied by a gaggle of paps ... who hit KK with a slew of Rob Kardashian early exit wedding questions.

The Kimye wedding/honeymoon international tour stretched across Paris, Florence, Ireland and even Prague.
