Rihanna made sure that Eminem's opening performance during the MTV VMAs had even more heat. The R&B stunner joined the hip-hop maestro on their duet 'Love the Way You Lie.' What was even more shocking was how Rihanna -- normally a fashion-forward thinker -- paid tribute to other music giants in her wardrobe choice.

Rihanna's red hair seemed ripped from the technicolor variety Katy Perry has kept on constant rotation all summer long, while her wedding dress was pulled from the rack of the 1984 MTV VMAs when Madonna shocked the world with her 'Like a Virgin' performance.
