Miranda Kerr has been snapped in a revealing outfit while frolicking on a Sydney beach.

The Australian supermodel was shooting an advertising campaign for her skincare range, Kora Organics, at the weekend when she was photographed in a see-through white dress and lacy underwear.

Kerr was performing cartwheels and dancing with a group of young girls for the ad shoot at Palm Beach.

It was during a cartwheel that Kerr was photographed at an unfortunate angle, with her underwear barely covering her private bits. The photos have been published on the website of an English tabloid.

Kerr tweeted photos from the shoot and wrote: "Thank you again to the #A-team who worked on my KORA campaign (sic)."
