Cristiano displays his muscles

Cristiano Ronaldo has stripped down to his smalls to promote his second CR7 underwear collection.

The footballer, 29, shows off his hot ripped body in the Rankin x Ronaldo For CR7 Underwear campaign, which was shot by famous fashion photographer Rankin.

Shots of Cristiano in his new range were projected onto iconic locations in seven capitals – London, New York, Berlin, Lisbon, Paris, Milan and Madrid – this weekend.

In the photos, Irina Shayk‘s man displays his rather impressive bulge in blue, orange and patterned black boxers and a tight pair of form-fitting black briefs.

His dark hair is slicked back into a sexy quiff and his arm and leg muscles are on full display, alongside his rippling six-pack.

Dad-of-one Cristiano – who’s created more designs for the autumn/winter 2014 season with menswear designer Richard Chai – is thrilled with his latest pieces.

‘I am really proud of my second CR7 Underwear collection and wanted to launch it in a way that was personal to me, and to have some fun with it,’ says Cristiano.

‘The number seven has always been close to my heart, so I was honoured to unveil my new collection in seven cities around the globe.’
