A wedding ring-less Kim Kardashian was photographed leaving for Australia from Los Angeles International Airport Monday night, the same day that the reality star filed for divorce from Kris Humphries.
Kardashian, 31, told PEOPLE over the weekend, before her divorce was made public, that she stepped out solo for Halloween in New York City because she was flying to Australia the next day.
She is expected in Sydney on Wednesday to launch her Kardashian Kollection purse line with a party at Hugo’s Lounge.
