In bed with Irina Shayk: Ronaldo's supermodel girlfriend stars in sultry new underwear ad

It is little wonder Cristiano Ronaldo is regularly seen with a huge grin on his face if this is what her wakes up to each morning.
His girlfriend, supermodel Irina Shayk, is showing it all off in a new campaign for Italian underwear designer Intimissimi.
In the sultry new adverts the 25-year-old bares her enviable figure in a sexy black push-up bra and matching knickers as she lounges around on a bed.

The Russian-born beauty stares into the camera and plays with her hair provocatively in one of the frames.
 In another she accentuates her now famous curves by pushing her chest up seductively.
Clearly not shy of showing it all off, the model recently posed completely nude for fashion giant Marc Jacobs.

Curves: Irina showed off the body which landed her the coveted Swimsuit Edition cover

She 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' - her famous long legs - in typical style.
It has been a successful year for the model professionally after she bagged the coveted Sports Illustrated Swimsuit Edition cover back in February.

Irina has been dating Real Madrid midfielder Cristiano Ronaldo since the beginning of last year and the pair have become inseparable with the footballer even flying to New York for one night to celebrate Irina's Sports Illustrated success.
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 Real Madrid.
