James Blunt's wife was convinced he had won Celebrity Traitors

James Blunt’s wife, Sofia Wellesley, spent months believing her husband had triumphed on The Celebrity Traitors, only learning the truth when the final episode was broadcast.

Blunt made it to the last three of the BBC competition before being banished by the show's eventual winners, Romesh Ranganathan and Sebastian 'Bash' Croft.

The singer was not allowed to reveal the outcome to his wife because of the programme's strict rules, and he kept the secret until viewers saw the finale for themselves.

The 52-year-old told The Sun newspaper: "You’re not supposed to tell anyone anything. And I’ll tell you how good I was - my wife genuinely thought I’d won. I didn’t tell her the result. In fact, I told her nothing at all."

He said: "Even as she was watching that final episode and everything was being revealed, she was blown away. I signed my NDA [non-disclosure agreement], and I stuck to my NDA!"

James went on to admit filming the show was a tough experience.

He also revealed that producers played the haunting Hunger Games song, The Hanging Tree with vocals by actress Jennifer Lawrence, before filming at the Round Table and he still struggles to listen to the track.

He said: "It’s a marathon and at times, a terrible experience - but wonderful to finish. When they sat us down at the Round Table, viewers didn’t get to see that they played a song [The Hanging Tree] just to psych us out."Someone sent it to me afterwards and my wife said: 'Wow, you’re quite traumatised by hearing that'. I actually started sweating and shaking."

James has also addressed rumours of a feud with his Celebrity Traitors co-star Romesh, who helped dump him from the show at the last minute.

Speaking on Hits Radio, James said: "Romesh is a very, very sweet human being, and I promise he and I get on very, very well."

Asked if Romesh donated any money to James' preferred charity, the musician said: "He has done. I was going to save that for a conversation I was having with him, but you know, if you’re going to mention it, he absolutely has. It’s called the Blue Marine Foundation."

Romesh, 48, and Sebastian, 24, took home the £83,000 prize pot. The winners previously declared they had agreed to split their winnings between Choose Love and the Refugee Council.
