Khloe Kardashian was once a blonde bombshell and RadarOnline.com has the photo to prove it!

Khloe, 27, uploaded nearly 100 photos to her official blog over the holidays showcasing photos from past Kardashian/Jenner Christmas Eve parties — and one in particular shows a thin, blonde, almost unrecognizable Khloe.

"Merry Christmas Eve my dolls!!!!!!! As I’m sure many of you know, it’s a Kardashian Jenner family tradition to host a Christmas Eve party every year at my mom’s house," Khloe wrote on her blog.
