Shayne WardShayne WardOh dear. Technology can be a marvellous thing...

But not when it goes wrong.

X Factor winner Shayne Ward has been firing off naughty text messages to his celeb pals, including Robbie Williams and Simon Cowell.

And the recipients of the X-rated "sexy fun" messages weren't amused.

According to The Sun, angry stars have been calling up 21-year-old Shayne to ask what on earth is going on.

But it's not poor old Shayne's fault. His phone was infected with a virus which sent the rude texts to people in his contacts list.

A source said: "Shayne is dying of embarrassment."

He even got a clip round the ear from fellow X Factor contestant Brenda Edwards...

Ouch.

We're not laughing, Shayne, honest.
