Kelly Osbourne looks super-slim and sexy on the latest cover of US Weekly. The rock spawn and former reality TV star says she got more flak for being overweight than for being a "raging drug addict." We aren't surprised. In the Hollywood hierarchy of sin, fat is up there on the list of no-nos along with being a bad mom, being a boring interview or dating John Mayer. Drug addicts get the glory, attention and sympathy while little Miss Fattie Pants has to hope some diet company will offer her big bucks to slim down on their product, pray for results and then appear scantily clad on the cover of a magazine (we're looking at you Valerie Bertinelli!). What's the root cause of this discrimination? We here at PopEater think the problem is threefold -- our explanation is after the jump.
