James Blunt once got drunk with Ed Sheeran in an "old brothel".
The 43-year-old singer-songwriter and Ed, 26, are poised to spend three months on tour in the US, but James has promised there won't be a repeat of their previous shenanigans after an awards ceremony in Australia.
He shared: "I'm touring for three months in America with Ed Sheeran, who I watched play the Teenage Cancer Trust's gig at the Royal Albert Hall in London last night. He seems to be doing all right.
"Then I start my own world tour, kicking off around Europe and the UK in October.
"But me and Ed are going to take ourselves very seriously, it's all about work. It won't be a repeat of that time we got really drunk at an after-party following an Australian awards ceremony."
At the party, James stumbled home after returning from a trip to the toilet to find that all of the guests, including Ed, had gone.
He told The Sun newspaper: "It was in an old brothel, a non-functioning one. We were hammered. I went to the loo and when I came out, the whole place, which had been full of 1,000 people, was totally empty. Even Ed had gone. I went out and the sun was up and I stumbled home."
Meanwhile, James claimed recently that he and Ed made up the story about Princess Beatrice cutting Ed's face with a sword.
The pair hit the headlines in November when it was reported that Ed had been struck in the face with a sharp weapon by the royal as she was pretending to 'knight' fellow musician James at a party at the Royal Lodge in Windsor.
But the 'You're Beautiful' hitmaker has since said they fabricated the story in order to cover up the fact that Ed had simply cut himself whilst drunk.
James explained: "Ed was drunk, messing around, and he cut himself. We made a fancy story up; people fell for it. It was very embarrassing."
