Former world no.1 tennis player Caroline Wozniacki is sizzling on and off the court having released new pictures wearing nothing but her own underwear line.

Wozniacki released her own brand of smalls last year but as the business savvy will do she has leaked another batch of snaps just to keep interest piqued and the ball rolling.

It's likely to work as these pictures will no doubt be flying around the internet all day.

The girlfriend of golfing superstar, Rory McIlroy has been showing good form on the court as well recently.

Just last week the 22-year-old was beaten by Maria Sharapova in the BNP Paribas Open final last week.

But it is likely the underwear photo shoot will draw more column inches.

Teaming up with Danish company JBS, she named the range 'this is me'.

Wozniacki says: 'What I wear reflects who I am.

'That’s why I chose to create my own underwear collection for the girl who wants the good looks from fashion, a perfect fit for her body, and a quality that’s hard to beat.'

She filmed the shoot for good measure.
