The heartthrob pop star ' who has previously offered £1 million to promote extra-small condoms ' shocked fans by revealing all about his apparently tiny manhood on stage at a concert at the Rod Laver arena in Melbourne, Australia, after one fan commented on his "good looks".

He said: "What does Spanish good looks have to do with the size of your penis? Maybe I have the Spanish looks but I have the smallest penis in the world. I'm serious."

The 36-year-old - who has been dating former tennis player Anna Kournikova for almost 10 years ' also revealed he didn't lose his virginity until he was 25, but he then claimed he was 17 and it lasted 10 seconds.

After inviting three men on stage, he told them and the rest of the crowd: "I grew up with a lot of my friends and all of them lost their virginity with hookers, not that there's anything wrong with that.

"They had to pay for it. I wanted to wait for the right girl so I waited until I was 25. I was nervous as s**t the first time. Usually the first time is not the best. Let me be honest, I was 17-and-a-half, I was so nervous. It lasted ten seconds."

Enrique had been suffering from a fever before the concert and had almost decided to scrap the performance because he had been feeling so unwell.

The singer ' whose crooner father Julio Iglesias claims he has bedded over 2,000 women - has previously revealed a desire to increase the size of his manhood because it is "way, way, way too small".

He said: "I'd change my penis if I could. It's way, way, way too small. I can never find extra-small condoms."
