Trina got down and dirty, shooting the video for her new single “I’m Back (Back 2 Business)” in Miami on Monday. The Diamond Princess rounded up some of her sexy gals and hosted a car wash. The ladies turned heads as they washed Maybachs, Ferraris, and other luxury whips in their short shorts, bikinis, and Louboutins. Trina flaunted her curves while rocking one of Lil Wayne’s TRUKFIT hats and straddling a motorcycle.
