Irina Shayk poses nude

Dating a footballer has certainly sent Irina Shayk's profile soaring into the stratosphere. And Cristiano Ronaldo's girlfriend's latest endeavour is posing nude for esteemed fashion designer Marc Jacobs. The Russian-born model, 25, stripped off to appear on the latest T-shirt for Jacobs' Protect The Skin You're In campaign. In the photo she poses with her back to the camera, showing off her 'talents' - i.e. her famous long legs - in typical style.

Since 2008, Marc Jacobs has convinced several stars to shed their clothes for the campaign, in partnership with the NYU Cancer Institute. Notable faces (and bodies) include Dita Von Teese, Victoria Beckham and Marisa Miller who have all had their naked bodies printed on t-shirts in the name of charity.

It's been quite a year for the 5,10' model who bagged the cover of Sports Illustrated's infamous swimsuit edition back in February. Irina has been dating midfielder Cristiano Ronaldo since the beginning of last year. The 26-year-old football superstar is renowned for dating models, having previously been in relationships with busty Nereida Gallardo and former Hollyoaks actress Gemma Atkinson.

Now with a child fathered by a surrogate mother, Ronaldo seems to have settled down setting up home in Spain where he plays for First Division side La Liga. The football playboy appears to be happily settled with his stunning girlfriend too.
