Stefano Gabbana recently admitted via Twitter that he has no idea who Stella McCartney is. Now if that's not a slap in the face for Stella I don't know what is! The Gabbana half of the Dolce & Gabbana design duo revealed his lack on knowledge during a twitter conversation with friend Fabio Viscovo on Tueday. Stefano tweeted (in Italian, kindly translated for us by Humor Chic) 'Stella McCartney who...the daughter of a musician?', 'What's she known for?? What's her speciality??' before basically calling her a 'nonentity'! Wowsers Stefano, don't hold back there. Obviously Stella's catwalk and hugely successful collaborations with Gap Kids, Adidas and Target hasn't made big news in Italy. Stella has been tight lipped on the twitter front, perhaps taking the higher path and excusing Gabbana's ingorance!
