James Blunt's wife Sofia Wellesley shares rare loved-up snap as she congratulates him on landing his first number one album in 19 YEARS after she signed him up for Celebrity Traitors

James Blunt's wife Sofia Wellesley posted a rare loved-up snap on her Instagram to congratulate him on landing his first number one album in 19 years on Friday.

The singer, 52, officially secured his third number one album for his new album Airplane Mode on this week's Official Albums Chart, since 2007's All The Lost Souls.

Sofia, 43, gushed she's 'so proud' as she cosied up to James in the sweet snap following his Celebrity Traitors stint. 

Poking fun at James, Sofia also insisted that she's 'not changing her name' after he vowed to legally change his surname to Ryan Air if his album hit number one. 

She captioned her post: 'Number 1. So proud of you. I'm not changing my name though.' 

James and his attorney wife Sofia, who is the granddaughter of the eighth Duke of Wellington, married in 2014 and they have two children. 

'I can't tell you how grateful I am to every single person who has gone out there and downloaded, or bought, or streamed my album,' James told Official Charts.

'From the bottom of my heart, thank you so much! I'm going to get absolutely pissed!' 

Last week, James revealed that he had never watched Celebrity Traitors and shared that his wife was the one to sign him up. 

When he was asked on Good Morning Britain if he was 'cashing in' on his stint with the release of his new album, Airplane Mode, he said: 'You're so cynical to think I would cash in on the Traitors. 

'No, I'd written and recorded the album and then the offer for the Traitors came and then my manager said no to the Traitors team. He didn't bring it to me.

'My wife signed me up without telling me. She just said: "Hey James, Claudia Winkleman has been in touch and I've signed you up for the Traitors".

'I hadn't watched it and didn't know anything about it. I think you can tell that when I'm playing the game.'

James, who was a Faithful, joked: 'In years to come they'll be studying my strategy. I still got to the very end by blundering through and apologising profusely.

'It's a survival game and a guessing game. It was great fun.'

After filming in the Scottish Highlands, James returned home but kept what happened on the show strictly under wraps. 

He said: 'I didn't tell a single person. As we watched the final episode, my wife turned to me and said: "I thought you'd won".

'She was so disappointed in not only what had happened but also in me.'

During the final roundtable, James was within touching distance of taking home a share of the prize money, but was blindsided when Romesh Ranganathan questioned his Faithful status.

James insisted Romesh was 'entirely wrong' but it was only when Sebastian Croft took him aside to defend James, did the comedian concede and voted King Kenny out. 

Following Kenny's banishment, viewers knew that this meant there were only three Faithfuls left in the game, and Sebastian and Romesh both voted to end things there. 

James sealed his fate though when he voted for another banishment, meaning it was inevitable that the other two would vote for him to be eliminated. 

The singer addressed rumours of a feud with Romesh during the interview. 

He said: 'I did get Romesh's number and I did text him and say: "I know where you live". We are actually really good friends and I'm going on his podcast soon. It is just a game but it is so intense in that moment.' 

James also said James Acaster didn't out himself as a Traitor at the roundtable and instead insisted the comedian was cornered by himself and Michael Sheen over their murder in plain sight theory. 

He said: 'We got him, we pinned him down. Michael and I had discussed what had gone on with the murder in plain sight and we were nailing him to a post. We caught him. It felt like being in a TV film where we'd got our guy and cornered him.'
