Los Angeles: Pop star Rihanna will reportedly work with fashion designer Stella McCartney for next collection.
McCartney, 40, met the Umbrella hitmaker two years ago and is now thinking of collaborating on a fashion range.
"They have been having regular chats," showbizspy.com quoted a source as saying.
"They call them `mood calls`. Stella rings Rihanna and asks her to explain what has influenced her mood that day - colours, textures, patterns. 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," the source added.
