Potts, who has also landed a record deal with Simon Cowell, the TV show judge, said of fixing his teeth: “I’m not sure about veneers but I do want to get the crown repaired. It would be nice to be able to smile naturally. I feel very self conscious about it at the moment. But whatever I do I’m not going to change who I am.”

You can see a more confident Potts in his deal-clinching performance of Nessun Dorma.

Mr. Cowell: Please make sure you get a good orchestra and engineer. I’m looking forward to this album.
