'It's my secret,' whispers Eva Mendes in her new advertising campaign. But what isn't secret is her body - which has caused outrage across America.
Her 30-second advert for new perfume Secret Obsession has been banned by U.S. networks after being deemed far too racy for TV - because it shows a brief glimpse of Eva's nipple.
In the black and white advert a mostly bare Eva rolls around seductively in an unmade bed. At one point the 34-year-old caresses herself, offering observant viewers the quick glimpse of her chest.
'Between love and madness lies obsession,' she whispers. 'Love...madness. It's my secret.'
Calvin Klein bosses don't seem upset by the controversy, posting the advert on their website under the headline 'Eva Mendes banned advert'.
'This development is not entirely a surprise for the U.S. market,' said Tom Murry, president and chief operating officer of Calvin Klein Inc.
'We believe the commercial is exceptional and hits the mark for Secret Obsession. We will reach our consumers in the U.S. primarily through the Web site, the print campaign and at point of sale.
'We are anticipating a very successful global launch.'
Eva previously exposed her body in the 2007 film We Own The Night. She told interviewers at the time she was horrified by what her father might think.
'I told my dad. I said, 'Dad, Poppy you cannot be there on time. Nobody can.' It's a tough one. I understand.
'It premiered in Cannes and I'm sitting there in the audience and I was like, "Oh my God, no that's me. Oh my God, oh my God. That's me. That's my boob, that's my boob."'
Since then Eva has overcome her embarrassment to bare all for animal rights charity Peta, in the 'I'd rather go naked than wear fur' campaign.
Back in 1995 Calvin Klein was investigated by the U.S. Federal Bureau of Investigation over whether a series of suggestive shots of young models was pornographic. And in 1980 a young Brooke Shields caused outrage whispering 'You want to know what comes between me and my Calvins? Nothing.'
And with her clothes on: Eva looks stunning at the premiere of We Own The Night
