Wow — a lot can change in 20 years.
Close gal pals since before they were even teenagers, Kardashian shared the picture with Instagram fans and captioned the pic: "#ThrowbackThursday @nicolerichie and I being oh so cool at 13 years old."
In the 20 years that have passed since that photo was taken both ladies have acquired many notches on their belt — Kardashian starring in a sex tape with ex-boyfriend Ray J that thrust her into instant fame and a reality TV show with her family that has caused more than a few controversial headlines, and after starring in The Simple Life with former BFF Paris Hilton and marrying Joel Madden with whom she has two children.
Engaged to baby daddy Kanye West, Kardashian remains close with Richie, who attended her star-studded baby shower last year.
Richie retweeted the photo mocking her own braces in the photo captioning it, "Brace Yourselves!"
