Sir Tom Jones, the Welsh superstar and judge on The Voice, has sparked concern among fans after they noticed a mark on his face during the first episode of the ITV show and urged him to get it checked by skin specialists. One person commented on X, formerly Twitter: "I hope Sir Tom has had that brown mark on his face checked out," while another viewer asked: "What's that new spot on Tom's face? Hope it's ok." Sir Tom took to social media after the show to comment on a performance with contestant Stan.
