Revealing: Supermodel Heidi Klum wears a very risque dress as she arrives on the red carpet at the 2012 MTV European Music AwardsImages

Heidi Klum may have been the hostess of this year's MTV Europe Music Awards, but she certainly wasn't winning the battle of the red carpet.
For her first of many outfits at the star-studded ceremony in Frankfurt, the 39-year-old left little the imagination in a revealing dress.
The mother-of-four showed off a lot of cleavage in the lace-up blue and gold studded Versace gown as she arrived on the red carpet.

Outfit change: Heidi changed into a cream strapless dress with a large puffball skirt

'So they have got me beautiful outfits, great shoes and great jewellery, but it depends how much time I have to change in between (hosting) because it's all live.'
It wasn't long until Heidi had her first outfit change and changed in to a cream strapless dress, with cut-out detailing.
The top half of the dress, which appeared to be woven, turned into a large puffball skirt.
She completed the look with a bizarre top hat and leather fingerless gloves.

Ahead of the awards, Heidi and PSY had been practising the Gangnam Style dance.
In a Twitter photo, Heidi was seen wearing PSY's signature blue suit and glasses as she enjoyed a masterclass with him.
Heidi admitted she regularly performed the dance with her four children.

British singer and daughter of Bob Geldof, Pixe Geldof opted for a completely contrasting look to host Heidi.
She covered up in a full-length, long-sleeved dress, which appeared to be knitted, in a range of autumnal colours.
