The `She Wolf` hitmaker admits she only realised how strong her cravings for the sugary treat were when she woke up tearful after dreaming of it while dieting to get in shape for a music video.
She said: "I love chocolate. I`m addicted to it. Do you know when I realised that? Shortly before we started shooting the video for `She Wolf.`
"I needed a whole month to get back into shape. I danced, worked out and had to stick to a strict diet - only fish, spinach and a specially-prepared dessert with tofu. For the first time in my life I was dreaming of chocolate and cake and always woke up with tears in my eyes."
However, the Columbian-born beauty made sure she made up for her deprivation as soon as filming the video was complete.
She added to website Tagesspiegel.de: "When we finished shooting the video I went to a cafe in Los Angeles and had five pieces of chocolate cake in one go!"
