After 20 years as a top model, Heidi Klum has a photo in her album for every occasion.

And the model was obviously feeling cheeky today, tweeting a vintage shot of herself leaning into a car and flashing her gold underwear.

The blonde model gave no hint as to the picture's provenance, writing simply 'whoopsie' in the caption.

Former Victoria's Secret angel Heidi still commands huge fees as a model, but concentrates on her work as a presenter, hosting Project Runway.

The 39-year-old also tweeted a picture of herself in front of a huge plate of pizza, commenting 'carb'ing it up'.

She took a delicate bite of the cheese pizza, but despite her comment did not look ready to demolish much more.

While her status in the industry is such that she no longer needs to watch her diet as closely as she once did, Klum can not afford to overeat.

The mother-of-four has been in New York's West Village with her children Leni, Henry, Johan and Lou.

She is currently undergoing a divorce from husband S! eal.

The couple announced their separation in January, less than four months before their seventh wedding anniversary.
