Ed Sheeran forgot the lyrics to some of his songs as he made his comeback with new music after a year away.
The star, 25, took a year-long hiatus, from the music scene and social media, in 2016.
On Friday he played his new music - Castle On The Hill and Shape Of You - on the Radio 1 Breakfast Show.
In his first radio interview in two years, the singer admitted that next time he takes a break it will be shorter.
Sheeran realised he could not remember the words to some of his songs when Don't and Sing had come on the radio.
"I've relearnt everything. I spent a day relearning the words. Next time I take a break it will be two weeks not a year," he said.
Concerning his travels, he said: "I specifically picked places where I wasn't really liked...No-one really cares about me in Japan. There are like two people that like me in Japan."
Sheeran is still sporting a scar on his face following reports that Princess Beatrice accidentally cut him when a party prank went wrong when she pretended to "knight" singer James Blunt with a ceremonial sword.
He said he did not know whether he was allowed to talk about the incident but joked about the scar: "Do you like it? I think it's quite rugged. I have been telling people that it was James Blunt, trying to get the pop career back.
"He's been telling me to say that. I'm not being mean. He's such a nice guy."
New track Castle On The Hill is described as a "love song for Suffolk", which Sheeran penned in mid-2015.
Sheeran shot the music video in Suffolk with all the extras from his former High School.
Sheeran's new album is called ÷, following the huge success of + in 2011 and × in 2014.
He described the album as "schizophrenic", featuring "lots of different sounds".
The singer-songwriter spent a week with an Irish folk group who stayed in his house to record one of the tracks.
At one point he had "25 people" staying in his six bedroom mansion making music, admitting it was "quite crammed".
The Game Of Thrones cast were some of the first people to hear his new tracks, before they were released, as Sheeran admitted he likes playing his music to "randoms".
"I ended up going to a party where a lot of the Game Of Thrones lot were at. They all ended up back at my house. I'd never met some of them before and said 'do you want to hear some of my songs?'"
Sheeran's return comes after he posted a short video of himself on Friday holding up a sign reading: "New music coming Friday!!"
