Heidi Klum has shared a cheeky snap of her flashing her knickers on Twitter.

The 39-year-old German-born model treated her 900,000 followers to the vintage photograph, which shows her leaning into a car and flashing her gold underwear.

It is not known when the picture was taken but the former Victoria's Secret model's famous long legs look as toned as ever.

Klum captioned the image with the simple message "whoopsie".

The mother of four has been showing off her curves at every opportunity following her split from her husband Seal earlier this year.

She recently became the latest star to join the celebrity body-surfing craze after posting a snap of her bronzed, toned body in a revealing two-piece.

Klum is filming the 10th season of Project Runway for the Lifetime network.
