The Chanel creative director - who has claimed his remarks calling the singer ''a little too fat'' were taken out of context - insists that although Adele is a ''beautiful girl'', she needed to lose weight because she was ''a little roundish''.
Speaking on CNN's 'Fashion: Backstage Pass', he said: ''I never said that she was fat, I said that she was a little roundish. A little roundish is not fat. But for such a beautiful girl, after that she lost eight kilo [17.6 pounds], so I think the message was not that bad.''
Following Karl's comments last year, Adele, 25, insisted she had never aspired to be stick-thin.
She said: ''I'd lose weight if I was an actress and had to play a role where you're supposed to be 40 pounds lighter, but weight has nothing to do with my career.
''Even when I was signing [a contract], most of the industry knew if anyone ever dared say [lose weight] to me, they wouldn't be working with me.''
