Just a few months after making his comeback to the judging panel of ‘The Voice UK’, legendary singer Sir Tom Jones is believed to be considering quitting the reality talent contest after the end of the current series.

The 76 year old crooner was famously dropped by the BBC for the final series on the network in 2016, in what was widely criticised as an unpopular move.

He has been praising the format changes made on the revamped show on ITV, after he was restored to the judging panel alongside newcomers Jennifer Hudson and Gavin Rossdale, but a new report in The Sun suggests that the hectic filming schedule has worn him down and forced him to re-think his future with the show.

“Tom has really loved being back on ‘The Voice’, and is having a great time working with the other judges and the entire team,” an insider told the publication on Sunday (March 5th). “They all get along famously behind the scenes, as well as on camera.”

“But there’s no denying that filming show is very hard work, and takes up a huge amount of time and energy. Tom has really felt that this year. He has found it very tiring. And he has been overheard telling his team that he ‘already knows’ he won’t be back for the next series, because it takes too much out of him.”

The source continued: “After being so unceremoniously dumped from the BBC show, Tom returned to ‘The Voice’ on ITV with a whole new enthusiasm. But while he has thoroughly enjoyed himself, that has come at a cost. And at the moment he seems to feel that he would like to go out on a high.”

Famously, the Welsh singing legend told the BBC to “go f*** themselves” in late 2015 when he discovered he was to be replaced with Boy George in the 2016 season, after not even having consulted him about it.

“I was p***ed off,” Jones said at the time. “I never got to the bottom of who made the decision. It was between the production company Wall to Wall and the BBC, and I still don’t know why.”
