Ed Sheeran used to hang around while unclean on London Underground trains because he didn't have anywhere else to go.
The Lego House hitmaker - currently supporting Taylor Swift on her Red tour - admits he would go days without washing when he began his quest to become a musician and would be forced to sit on Tube trains all day.
Speaking to the Daily Star he said: "Sometimes when I didn't have a place to shower, I'd wait for the Tube to open up at 5am and sit on the Circle Line and go round and round. I wouldn't shower.
"I couch surfed and floor surfed sometimes. Once I was staying at this student house and had a shower but didn't have a towel.
"This lad had a Green Day poster, I literally just scraped the water off with it."
The 22-year-old singer - who has been romantically linked to Selena Gomez - claims since becoming a global star, his cleanliness has improved.
He said: "Now, I shower every day."
