PHOTOS: Fergie Looks Fierce on Black Eyed Peas Tour

Fergie moves it and shakes it in a revealing black number while belting out tunes during a Black Eyed Peas performance last night at the Mandalay Bay Events Center in Las Vegas. The chart-topping group is touring in support of their album The E.N.D. The Dutchess has also been very busy promoting her new movie, Nine, in which she plays a seductive prostitute.
