Ferrell caught by wife in sexy pose with Klum

Will Ferrell and supermodel Heidi Klum were recently left red-faced at a photo shoot - after the comedian's wife caught them in a compromising position.

The unlikely duo recently got carried away while modelling for US magazine 'Sports Illustrated's annual swimsuit issue to promote Ferrell's new basketball comedy Semi-Pro.

The actor insists wife Viveca Paulin chose the worst possible moment to walk into the studio.

He recalls: "My wife walked in right at the moment when I was biting Heidi's butt. But she is incredibly accepting of all these things. She just rolled with it."
