Do we ever!
It"s common knowledge that Kim Kardashian used to show up on event lists as "Paris Hilton"s guest." Heck, even she"ll post a good throwback photo co-starring Paris Hilton, acknowledging monokinis and wraparound sunglasses.
Yours truly came across a few old photos of Kardashian and her family (Kris Jenner, Kourtney and Khloe specifically) partying with the reality star and Hilton at Tao in October 2006.
SO. MUCH. FUN.
I threw a throwback photo of Kyle Richards and Faye Resnick in for good measure. They"re all basically the same person, amiright?

 Entourage was the very embodiment of 2006: The dawn of a shitty era for humanity, but an epic one for the likes of Hilton, Lohan and other douche bags they ran with.
