In order to avoid a red carpet Hindenburg, Anne Hathaway abandoned her plans to wear a "pink embroidered tulle illusion gown" by Valentino to the 2013 Oscars, opting instead for a pale pink Prada column gown that clashed with her Tiffany necklace and made it look like her headlights were permanently on.
So why'd she do it? Apparently, because her 'Les Miserables' castmate Amanda Seyfried's silvery Alexander McQueen dress was too similar to Anne's original choice.
But in the world of Hollywood, you can't just make a last-minute switch like that without insulting some very important people. And so ... Gowngate was born.
