Sir Tom Jones may be a coach on The Voice UK, but he doesn't rate its contestants' chances of hitting the big time.
The music legend has mentored aspiring artists on five series of the ITV (and formerly BBC) talent contest.
But unlike rival The X Factor, it has always struggled to make stars, with even its winners proving chart flops.
And the 'It's Not Unusual' singer believes it's harder than ever for anyone to crack in to the industry.
When The Mirror asked how he'd advise wannabes, Sir Tom joked: "Forget it. Do you have a plan B? It doesn’t seem as easy as when I started.
"My advice is at a performer is to listen, keep your ears open and take advice and don’t shut yourself off.
"Don’t be shut off and think, 'this is what I’m going to do'. You just be true to yourself. You have to find your way you like to sing."
The most successful Voice winners are Andrea Begley, who charted at seven with debut album 'The Message', and Stevie McCrorie, whose single 'Lost Stars' reached number six.
Last year's champ, former Liberty X member Kevin Simm, hasn't fared so well - with his latest album failing to chart.
The current series of the show reaches its live final this Saturday and Sunday, with Tom hoping his last remaining act, duo Into The Ark, will take the crown.
They're up against Will.i.am's hopeful Michelle John, and Jennifer Hudson's top two, Jamie Miller and Mo Adeniran.
Gavin Rossdale is the only coach who does not have any acts remaining.
