Swimsuit siren Kate Upton has been the face of the sexy warrior princess with ample cleavage that has helped promote the video game 'The Game of War' to higher levels of success. Kate will no longer be that warrior princess. She is being replaced with a new face. American singer Mariah Carey will be donning sexy garb to advert the game, but speculation abounds on if Mariah can successfully replace the curvaceous blonde.
Who do you think is hotter, Mariah or Kate?
