Mariah Carey helps out at Pizza Hut

Just had a spot of lunch in Pizza Hut, and noticed that, currently, they're raising money for a world food charity. If you don't object to them putting five pence on your bill, they give you a special code to download a Mariah Carey tune as a thank you.

This caught out eye, though - it's the signature of Mariah Carey, "Ambassador of World Hunger". If she's the ambassador for hunger, does that make her one of the four horsemen of the Apocalypse?
