Well, lack of food can make you Cranky I guess

Victoria Beckham spiced up Wednesday night's Rock & Republic fashion show in L.A. when she reportedly screamed at designer Michael Ball before being dragged away by security.
Lowdown in New York reported that soccer god David Beckham's wife, the former Posh Spice - who designed a jean collection for the celeb-studded event - threw a backstage tantrum when Ball informed her that her signature pants, with a crown embroidered on the arse, were out of the show.
"Are you gonna put it in? You're gonna put it in!" she screamed at Ball, according to a Lowdown spy.
"No, I'm not!" he shouted back.
"I don't know why I'm even asking you," she shrieked. "I'm a part-owner in this company!" Says the spy: "He finally called security, and they escorted her out."

Ouch! You own part of the company and still can't get what you want? Sounds like the fashion designing career is going about as well as that singing comeback.
