The R&B sensation joins the ranks of George Washington, Barak Obama, Tyra Banks, Angelina Jolie, as well as recent addition Selena Gomez, at the museum's Washington, D.C., location.
As a nod to one of the singer's favorite designers, the Rihanna replica rocks the all-black Balmain ensemble -- lace corset, shoulder-padded blazer, and harem pants -- she wore to the designer's runway show during Spring 2010 Paris Fashion Week.
Besides her signature blond Mohawk and smoky eyes, the singer wears a bevy of bling, including a diamond brooch, a large gold-and-diamond ring, giant diamond earrings, and a tennis bracelet.
RiRi seemed happy to show off her wax double, posting a Twitpic preview of the sculpture on her Twitter page!
Today through Sept. 30, fans who stop by Madame Tussauds in Washington, D.C., and mention the word "umbrella" will receive a buy-one, get-one-free admission!
Meanwhile check out the much-hyped tattoo that didn't make it onto Rihanna's wax replica.
