Cristiano Ronaldo has defended his alleged playboy lifestyle by saying he is 100% professional during the season.

The Real Madrid striker also told Cadena SER that he is unattached at the moment.

The former Manchester United winger was linked with celebrity heiress Paris Hilton during pre-season after he left the Premier League.

Ronaldo told Cadena SER: "I'll be up front. During the season no one can point fingers because I am an exemplary sportsman, but vacations are there to enjoy and I do what you want. This is my belief."

"I've done more in my early-life. And no, I do not have a girlfriend now."

"I have suffered like everyone who has loved. I am a sensitive person and I cry for love."

Ronaldo is trying to recover from his injury to help lift Real Madrid out of a mini-slump. He is expected to be contention next week when Real visit AC Milan in the Champions League.
