Kate Upton -- 'Game of War' With Mariah Will Be Awesome!!! (VIDEO)

Kate Upton has given her stamp of approval to Mariah Carey replacing her as the face of the wildly popular video game, "Game of War: Fire Age."

We got Kate leaving LAX Thursday -- and looking smokin' hot -- and asked about Mariah stepping in as the company shelves Kate's seductive commercial. Kate couldn't be more gracious.

A lot of people find it weird that the company is veering from Kate to Mariah, and we're hearing it has something to do with music.
