Enrique Iglesias enjoys going skinny-dipping in secret.

The 'Heart Attack' hitmaker, who has been in an on/off relationship with former Russian tennis ace, Anna Kournikova, for 12 years, has revealed he loves stripping off and going for a swim when no one is watching.

The 38-year-old heartthrob took part in a Q&A at a Gilt City event in Miami, Florida, on Thursday night (19.12.13) and according to the Miami Herald newspaper, when asked about his hobbies, he said: ''I love the water. I love the ocean. I go water-skiing. I go fishing. If there's not a lot of paparazzi, I go skinny-dipping. I won't tell you where because it would ruin my career. There's not a lot to show off.''

He jokingly added: ''My worst defect is from my waist down. I'm sorry, no. I can be moody and I'm not a morning person. I'm definitely not a morning person.''

Enrique, who is the face of Atlantico Rum, previewed his new single, 'I'm A Freak,' at the event.

The singer also revealed he still gets very nervous before he goes on stage.

He said:'' I do. I get nervous all the time. I have a little rum just to relax. As long as I don't get too drunk that I forget the lyrics! I just try to have fun. You know what I try to think about? I say, 'Imagine this is the last show. This is the last time you are going to go up on stage and people have paid money to see you sing the songs that you wrote.' To me that is unbelievable because I would honestly do it for free.''
