Kim, 32, was pictured at Los Angeles' LAX airport late last night (1 June) and was flashing her diamond wedding ring on her left hand.
The star was dressed in all-black, apart from her nude heels, and tried to keep a low profile by hiding behind oversized sunglasses.
However, Kim did take time to sign autographs and accept wedding congratulations for fans.
On 24 May, Kim and Kanye married at Fort Belvedere in Florence before later flying to Ireland for their honeymoon.
But after only several days on the Green Isle, Kim and Kanye cut their honeymoon short and headed to Prague to attend a friend's wedding.
It is not known why Kim has flown to LA without her new hubby, although it is believed he has already headed to Texas to prepare for his headlining gig at the X Games, which kicks off on Thursday.
Following the couple's wedding, their daughter North returned home with Kim's grandmother Kris and the rest of the clan. No doubt a big reunion is on the cards for the newlywed mum and her baby girl!
