R+B star Rihanna refuses to be content with just taking the music world by storm - she has big plans for the Rihanna brand. The Umbrella hitmaker admits she is never satisfied with what she already has, but is excited about mapping out her future - which included her umbrella-branding deal with Totes. Speaking at the Mobo Nominations Launch on Wednesday (22Aug07) in London, she says, "I'm never satisfied, never comfortable (with my career). I'm very ambitious. There's always more that I can do. "I wanna do movies, I wanna open my own businesses, you know that kind of stuff. The umbrella range is going phenomenally."
