Rihanna & McCartney London - Arabstoday Stella McCartney is taking inspiration from trend setting pop star Rihanna for her new fashion line. The British designer reportedly calls up the 24 year old star frequently to talk about her latest style inspirations as Stella is attempting to appeal to a younger generation of fashion lovers. A source told the Mail On Sunday newspaper: "They have been having regular chats. They call them 'mood calls'. Stella rings Rihanna and asks her to explain what has influenced her mood that day: colours, textures, patterns etc. Stella feels she needs to tap into a younger generation and Rihanna is happy to help. It's a bizarre way to create a fashion line but they work well together." Rihanna is currently the face of Sky Living reality show “Styled to Rock”, which sees aspiring designers pitted against each other in a bid to create a festival look for the singer.
