He might be one of the world's best footballers but that hasn't stopped Cristiano Ronaldo delving into the fashion world.

Real Madrid football star Cristiano Ronaldo launched the new campaign for his popular CR7 by Cristiano Ronaldo underwear collection at the weekend.

For the occasion large scale pop-up projections of the campaign images were installed across the world including New York, Berlin, Milan, Paris, Lisbon and Madrid.

The campaign is officially named Rankin x Ronaldo for CR7 Underwear, after the world famous photographer Rankin who shot the images.

"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," Ronaldo commented on the launch.

"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. It was a pleasure to collaborate with Rankin and incredible to see the images released in this unique way."

The collection is designed in collaboration with New York based designer Richard Chai.

This isn't Ronaldo's first brush with the fashion world, he made headlines earlier this year when he appeared on the cover of Spanish Vogue alongside model Irina Shayk.

He will also appear on the September issue of Men's Health sporting his underwear.

Ronaldo isn't the only footballer with a lingerie range; David Beckham has famously collaborated with H&M on an underwear collection.
