Heidi Klum bares all for cosmetics firm

Supermodel Heidi Klum has reminded estranged husband Seal what he's missing after stripping off for a daring new Astor ad.

The 38 year old looks stunning as the face of the European cosmetics company, wearing only multi-coloured body paint..

The German star recently confessed she's happiest when she's naked, telling Allure magazine, "I'm a nudist... I've never had a problem with my body."

Klum also bared all as the magazine's covergirl .
