Sean 'Diddy' Combs is marking his second Christmas behind bars, and the menu is a far cry from his days of champagne towers and celebrations with A-list stars. The disgraced rap mogul, 56, will be marking the holiday at Fort Dix in New Jersey, where he's serving his 50-month sentence for two counts of transportation to engage in prostitution. A spokesperson for Fort Dix exclusively tells Us Weekly that Diddy's day will start out like any other. Breakfast will begin as early as 6 a.m. and include Bran Flakes, whole wheat bread with butter and jelly, as well as a fresh banana and skim milk.
