As the star of a reality TV show, Audrina Patridge is no stranger to revealing all.

But these daring photos leave little to the imagination, as the 24-year-old poses on a sun-streamed beach for FHM.

Coinciding with the sixth series of The Hills, which boasts viewing figures of more than three million, Audrina is the face of the magazine’s Girls Of U.S.TV special.

Audrina, who was spotted leaving celebrity haunt Greenblatt's Deli in West Hollywood today, wrote on her blog: ‘Love to all my British fans! I’m on the cover … I’m the opening girl. So honored!’

Although she confesses that it wasn’t all plain sailing, adding: ‘It was so cold being in the water.

'But I hope you guys like the photos!’

Audrina, who is dating rock star Ryan Cabrera, also reveals that securing the part in The Hills – in which she stars alongside Heidi Montag, Lauren Conrad, Whitney Port and Spencer Pratt - was down to being in the right place at the right time.

The Californian, who also starred in last year’s slasher flick Sorority Row, joined the show in series three after being spotted lying by a swimming pool outside her apartment in LA.

‘I was sunbathing with my friend and this guy came over,’ she said.

‘We’ve had guys coming up to us and asking for our numbers so we just assumed he was one of those.

‘But it was The Hills creator Adam DiVello and he started talking to us and said I had a great look and would I be interested in being in his show.

‘When he mentioned it was reality TV, I was like, “No thank you, I’m not headed in that direction”.

'But then he said it was more of a soap documentary and I thought, “Well, it would be a good experience and get me used to being in front of the camera, so why not?”.

‘Five years later I’m still doing it.’
