Adele's recent heartbreak inspired her new album.
The 22-year-old singer - whose second record '21' debuted at number one in the UK album charts last month - admitted the end of her "amazing, immense relationship" helped her to write a whole host of passionate songs.
She said: "I had the most amazing, immense relationship. It didn't last, unfortunately - it stopped being fun, but thankfully the ending wasn't bitter. The whole thing changed me. It made me really passionate about love, life, me - pretty much everything."
However, after the success of her debut album '19', Adele was unsure how she could improve her second record.
She added to Reveal Magazine: "Before I went into the studio I wondered how on earth I was going to beat the first album. But it was like a tap that's difficult to turn off. The relationship I'd been in just consumed me, which is where the songs came from.
"It's important to me that people believe what I write about. They're honest and it's quite exhausting writing them because they're all about my emotions and me. I'd hate it if someone thought, 'Yeah, whatever, she has made them all up'."
