Real Madrid star Cristiano Ronaldo has been left red-faced over X-rated pictures.

The Mirror reports Ronaldo scored a ­spectacular own goal... after emailing X-rated ­pictures from a fan to his fiancee and dozens of friends and family.

The former Manchester United striker ­accidentally forwarded the explicit fan mail from a beautiful young woman to EVERYONE in his address book.

The Dutch fan sent Ronaldo flirty messages, including the five semi-naked photos he sent out, after ­obtaining his email address.

Other pictures in the email have her posing for the ­camera wearing a sexy tight T-shirt emblazoned with the words "too hot to handle".

Among those who ­received it were singer Pixie Lott, Hollywood ­socialite Kim Kardashian and ex-Big Brother star Imogen Thomas.

Since the embarrassing incident Ronaldo has been besieged with calls, texts and messages from confused friends.

"Cristiano's phone has been buzzing with calls and emails from bewildered pals in the past few days," a source said.

"They have all been ringing and messaging to ask what the hell the email is about. And of course they all want to know more about the girl in the pictures.

"He's had to explain she is just a fan who had sent him some pictures and that he made a mistake by sending them on instead of removing them.

"He is embarrassed about the whole thing and is particularly mortified at passing the email on to Irina.

"But he has done nothing wrong and luckily Irina hasn't confronted him about it.

"Wherever ­Cristiano goes in the world he gets ­women throwing themselves at him.

"And Irina knows dealing with other girls vying for his affection goes with the territory of ­being on the arm of a footballer like Cristiano.

"He is a bit red-faced about the whole thing and certainly won't make the same mistake again."
