Giorgio Armani has unveiled its latest underwear campaign featuring a rather muscular-looking Cristiano Ronaldo.

The football star is appearing for his second season as the face of Armani’s autumn/winter 2010- 11 adverts.

The ads were shot on location in Madrid by acclaimed snapping duo Mert Alas and Marcus Piggot.

The campaigns will roll out starting from July around the world on signature billboards in major cities such as New York, London, Paris and Tokyo.

The campaign will make its debut in Via Broletto, Milan on Thursday.

In addition to the print and digital campaigns, September will see the release of a commercial spot with Cristiano Ronaldo to showcase the collections.
