Heidi Klum's naked ease

Heidi Klum says being naked in front of her family is "not a big deal".

The stunning model - who posed wearing just underwear and a pair of wings for the recent Victoria's Secret fashion show - has no problem showing off her fabulous figure in front of her husband Seal and the three children they raise together.

She said: "To see me in wings is nothing too unusual. People are pretty open with their bodies in Germany and the children see you naked or in lingerie all the time so it's not a big deal for us.

"We don't hide inside a room somewhere and change - it's all very out in the open."

Heidi also revealed she not only has to maintain her slimline figure for work, but also to keep the romance alive in her marriage.

She added: "You have to work out to be sexy. People always ask me how I stay in shape and how do I do it and what really makes me do it is because I have a hot man waiting at home for me. So I don't want to be a slouch bag, I have to keep up appearances."
