Remember the days when Paris Hilton and Kim Kardashian were real friends? When they had matching handbags, hit up every club in Los Angeles and never missed a photo op? 

Those days may be over, but Hilton knew it was only right to match one birthday throwback message with another. 

On Wednesday, the former "Simple Life" star shared what's now a practically vintage photo of herself and her former BFF/assistant (who she never actually told to go clean her closet) on their 2006 trip to Australia. Kardashian had previously shared a throwback photo of their 2006 jaunt to Ibiza for Hilton's birthday in February.
