X Factor stars John and Edward Grimes are reportedly at the centre of a bidding war, with three companies hoping to buy the rights to their autobiography.

The Daily Star reports that the boys have been offered £250,000 for the book, even though they are only 18 years old.

The twins have also reportedly been offered a TV deal by the Disney Channel, as well as advertising deals for hair styling products.

A source said: “There are a lot of offers on the table and they are set to become one the X Factor’s biggest-ever success stories.”
