Adele's ex might not know about '21'

Adele has admitted that her ex might not know that he was the inspiration behind '21'.

The singer has managed to keep the identity of her ex under wraps.

'I have no idea if he's heard the record,' she tells PA 'or is kind of clever enough to link it, to think it's him

'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.'
