For those of us OLDS, you may remember that Kim Kardashian was Paris Hilton’s assistant back when she was just in her early 20s, and looked like this.

Now, 20 years later, she’s a billionaire, mother of 3, wife to this guy, much more famous than Paris Hilton, and just officially hit the big 4-0 — and looks finer than ever

A huge HAPPY BIRTHDAY to Kim Kardashian – 40 looks good on ya.
