Before they posed in front of the reality TV cameras, Kim, Khloe and Kourtney Kardashian were just three sisters goofing around for a candid photo.
Check out a nearly unrecognizable Kim and Khloe with blonde hair!
Kim posted the photo on her Twitter account today with the caption, "oldie but goodie." And while there wasn't a date on the photo, we know that Khloe was blonde while their father Robert was still alive (he passed away in 2003).
