R&B beauty Rihanna has been immortalised again for the Madame Tussauds Wax Museum in Berlin, Germany. The Umbrella hitmaker's look-a-like was unveiled on Monday (29Aug11) and features the star wearing a colourful ruffled leotard similar to the outfit she wore in the 2010 video for her David Guetta collaboration, Who's That Chick. The singer has previously had a wax replica of herself go on display in the Washington, D.C. branch of the tourist attraction.
