Recognize this brunette? No it’s not Lana Del Rey or Maria Menounos … it’s Heidi Klum!

Heidi is known for her stellar style, hit show "Project Runway" and blonde tresses. However, the 38-year-old mother of four took to her Twitter account to share a vintage photo which shows an almost unrecognizable teen Heidi -- with long brown hair!

"Wow! Check out this picture from 1992. One of my very first photo shoots," Klum tweeted with the photo Thursday. "This is my original hair color!"
