Eva Mendes says "love is the sexiest thing in the world."

The 34-year-old actress - who is dating producer George Augusto - admits she likes nothing more than being in a relationship.

Eva, the face of Calvin Klein's Secret Obsession fragrance, said: "My secret obsession is love. I love 'love!' I love being in love, and I love having someone be in love with me. Love is the sexiest thing in the world."

The actress, who is seen clad in skimpy lingerie complete with tousled hair, told America's OK! magazine: "To prepare for the Calvin Klein shoot, all I did differently was increase my cardio for two weeks because I wanted these images to look like my real, healthy body. I didn't want to show up looking like the skinny version of me. I wanted the real version of me up there."
