Austria's Next Top Model contestants forced to pose naked

The Next Top Model series is known for putting model hopefuls to the ultimate test in a bid to make it into the glamorous world of fashion.

And now a promo for Austria's latest series shows contestants being challenged to a very exposing situation, involving stripping down to absolutely nothing.

The clip shows the reality stars completely naked while on the set of a photo shoot.

And what's more, they're seen getting up close and personal with another model touching them all over, to get the picture perfect shot.

This challenge is very risque compared to other tasks contestants have been given in the past.

While challenges have previously involved swimwear or lingerie, being naked is certainly pushing the envelope.
