Adele has revealed her ex-boyfriend may not know he provided the inspiration for her new album.
The singer's painful break-up is recounted in the tracks on 21 - including the opening song Rolling In The Deep - but the Londoner has kept her former flame's identity under wraps.
"I have no idea if he's heard the record, or is kind of clever enough to link it, to think it's him," she said.
"I'm not saying he's dim. It's just that toward the end I don't think he felt like I loved him enough to write a record about him. But I did."
Despite her international success, the Grammy-winner - whose full name is Adele Laurie Blue Adkins - remains modest.
"I find it hard to say 'Oh, I'm a singer,' because my singers are Etta James and Carole King and Robert Flack, the all-time gurus, the gods of singing," she said.
"I used to be really stubborn and narrow-minded. I was very much a teenager - what I knew was all that I needed to know, and what I like is all that I'd ever like. Now I'm a bit of a sponge. I want to take everything in and learn about it."
