Eva Mendes has defended her controversial advertisement for Calvin Klein perfume, an ad that was banned from American TV screens for being too raunchy.

Mendes - who flashes her nipple in the ad - has spoken out about the ban, accusing American censors of promoting violence while continuing to ban nudity.

"I'm completely American, I was born and raised in America and I love it but I think we are too quick to censor nudity," Mendes told press during her current visit to Australia.
