Paris Hilton Wishes Kim Kardashian A Happy Birthday With Throwback Bikini Photo

The good ole days.

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. 

"Happy Birthday @KimKardashian🎂 Wishing you the best on your special day🎈What a fun trip we had in Australia, we loved rocking our matching #LouisBags. 👜👩🏼👩🏻👜 #BirthdayGirl 💖," Hilton captioned the snap. 

And while Hilton and Kardashian occasionally run into each other at events, their friendship never quite recovered after Kardashian's ascent to fame. These days, their relationship exists almost solely through flashbacks on Instagram. 

But in honor of Kardashian's 35th birthday, lets take a walk down memory lane:
