What's The Big Frigin' Xmas Difference?!

No one does Christmas quite like Kathy Hilton, and here to join THE Mrs. Claus of Hollywood is her very own ... Nicky Hilton! Only Kathy can pull off snaggin' Santa from the North Pole, but can you catch the minor changes in these two festive pics?

The two Hilton ladies dressed to the 9s and recently hit up the Flamingo Estate and Mytheresa Gingerbread House in Los Angeles and posed with a holly jolly Santa ... Can you handle the switch-ups? ... Don't get cold feet!

**HINT: There are THREE differences in the above Kathy and Nicky Hilton photos!**
