And as Madame Tussauds unveiled their new waxwork of Rihanna in Berlin, Germany, today, they had clearly based the figure on a previous incarnation of the singer. While the waxwork had Rihannas red hair, the singer has been wearing her locks curly recently, and more of an auburn colour - a change in appearance Madame Tussauds clearly hadnt anticipated. In addition, the garishly-coloured outfit the figure is wearing, which Rihanna donned in the David Guetta Whos That Chick video, also looks out of date, with Rihanna sporting more relaxed looks in recent weeks. Meanwhile, the video for Rihanna and Nick Minajs new video Fly has been released. Talking about working with Minaj, Rihanna said recently: 'She has a great buzz and she has a thing to her. She is a star and thats why people love her. Shes also really entertaining with her visual as well as her lyrics, and she has a great melody. Im really amazed that she can write like that. Nicki not only raps but she can write songs too...It was really easy actually. We were going back and forth with the texts on how we were going to get to do it because we were in two different places and had two opposite schedules.Minaj added: 'I wanted to work with Rihanna for a long time. Im very proud of her accomplishments: especially since she was born on an island like me. MO
