Rihanna demanded a haul of junk food for her globe-trotting 777 tour. The singer's backstage rider, obtained by Tmz.com, requested Oreo biscuits, gummi bears, sugary breakfast cereals, Red Bull, Coca-Cola, Sprite, and Flamin' Hot Cheetos at all seven shows on the week-long seven-country trek, which wrapped in New York on Tuesday night (20Nov12).
