Proving that top models don't have bad sides (and after 20 years at the top, who are we to argue?), Heidi posted this sexy pic of herself flashing her metallic gold lycra underwear with only the caption "Whoopsie".
While the hair and the car hint at an 80s or 90s origin, no clue was actually given as to when the photo was actually taken.
We do know, however, that the photo above is vastly different from one of the earliest photos taken of Heidi modelling, back in 1992 when she was just 19-years-old. Given she was a brunette back in 1992, we'd hazard a guess to say the photo posted overnight is perhaps from the mid to late 90s.
