X Factor twins John and Edward Grimes have reportedly been to see a Harley Street throat specialist, after coming down with flu like symptoms.

An insider told The Mirror: “The boys have been struck down by the curse of X Factor. There are lots of sniffles around at the moment and coupled with the pressure their voices are under, it’s no surprise they have got sore throats.

“They have been told to take it easy so that is what they are doing. The boys will be desperate to perform and everyone is hopeful they will be well enough to do so.”
