X Factor judge Louis Walsh will be back on the show this year and if reports are to believed, he will be sporting a new set of gnashers when he appears.

Simon Cowell has been trying to convince Louis to have his teeth done for years and until now Walsh has resisted.

However all that has changed and a show source told The Sun: “Yes, Louis has had his teeth done.

“He is very much looking forward to showing them off – though there is no way he was ever going to go as white as Simon.”

During the last series of The X Factor all of the finalists were sent for teeth whitening.

The source joked: “Dental hygiene and pristine teeth are two subjects close to Simon’s heart.”
