She became famous as a blond, but not many fans know that model/TV personality Heidi Klum‘s natural hair color is really brunette. That is until she tweeted a flashback photo of herself from one of her very first photo shoots in 1992 that reveals the now blond star as a natural brunette!

Heidi tweeted on Thursday, “Wow! Check out this picture from 1992. One of my very first photo shoots. This is my original hair color!”

She’s hardly recognizable back then with her shiny brown locks, but is still stunning with either brown or blond tresses!

Wow! Check out this picture from 1992. One of my very first photo shoots. This is my original hair color! twitpic.com/9bpbwr—
