Portuguese football superstar Cristiano Ronaldo isn't shy to show his great body in front of many people.

Like David Beckham, Ronaldo has created his own line of underwear. The 28-year-old football superstar who has just recently renewed his contract with Spanish football club Real Madrid was pretty thrilled and excited about the project.

He posted a photo on his official Twitter account on Thursday with New York fashion designer Richard Chai. The latter earned his practical experience in the fashion industry as Armani Exchange's assistant designer.

Ronaldo and Chai teamed up together from the very onset of making his underwear line which involves the styles, the colours, as well as the fabric chosen to create the garments. It is produced by Danish JBS Textile Group, the company which also produces tennis player Carol Wozniacki's underwear line.

Here's a video posted by JBS in its YouTube account which shows the behind-the-scenes for the upcoming advertising campaign of Ronaldo's underwear line. It was filmed in black and white and you will see the Santiago Bernabeu stadium. He was wearing nothing but his underwear and his cheeky grin. He may have a career being a model when he retires from football, after all.

It looks like Ronaldo made sure that his collection has a touch of his own personal style. It is named "CR7 Underwear," which stands for his initials and the number of the jersey he wears. His line is not limited to undergarments because the line also feature socks range. It is going to be officially hit the stores on Nov 1.

Well, it is not really that surprising to see him strip off. He has a great body, like that of an Olympian, and when his line finally opens, we will be seeing Ronaldo in his underwear streaked everywhere, that's for sure.
