Ed Sheeran's career is so successful that he's even taking a break from singing, but he didn't used to have the luxury. The singer-songwriter recently revealed how much he struggled before his debut album was released in 2011 in his new book A Visual Journey, revealing that he was homeless before he hit it big.

When the "Thinking Out Loud" singer was 16, he moved to London to study music. But after his course ended, he didn't have enough money to pay for rent, so he sometimes slept under an archway outside.

"There was an arch outside Buckingham Palace that has a heating duct and I spent a couple of nights there," he said. "I didn't have anywhere to live for much of 2008 and the whole of 2009 and 2010, but somehow I made it work. I spent a week catching up on sleep on Circle Line trains."

He tried to play it down by saying that it "wasn't that bad," but it still sounds like a pretty intense situation to us.

"I'd go out and play a gig, wait until 5am when the Underground opened, sleep on the Circle Line until 12, go to a session — and then repeat," he said.

Of course, things are totally different for him now. He's even performed for the Queen, when he used to sleep outside her palace. That's so crazy!
