The `Someone Like You` hitmaker has revealed her former lover - who she has refused to name - repeatedly called her claiming she owed him money for the songs she wrote on her debut LP about their failed romance. She is quoted by The Sun newspaper as saying: "For about a week he was calling and was deadly serious about it. "Finally, I said, `Well, you made my life hell, so I lived it and now I deserve it.` "He really thought he`d had some input into the creative process by being a p***k. I`ll give him this credit - he made me an adult and put me on the road that I`m travelling." Although it was released in 2008, `19` is now number three in the UK album chart following the success of her latest record `21` - which has spent 14 weeks in the top spot in Britain - while `19` and `21` are placed at number 20 and number one in the US chart respectively. Earlier this year, the 23-year-old singer admitted the tracks on `21` were inspired by her tumultuous love life, and specifically an "amazing, immense relationship" which came to an end. 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."
