Kelly was pictured in a striking silver gown as she walked the red carpet at the Nokia Theatre in Los Angeles, however she claims it didn't photograph well.
The Fashion Police star, who is famed for her quirky style, took to Twitter after snaps of her wearing the frock began to surface.
Kelly tweeted: ":( my dress did not photograph anywhere near as good as it looked in real life!"
Kelly's unusual frock featured a metallic bodice with long sleeves and a full grey tulle skirt. She wore her purple hair in plaits with a row of gold spike studs - similar to the 'do she rocked on Friday.
She completed her getup with a silver lightening bolt clutch bag and a pair of patent nude platforms.
Despite feeling glum about her outfit, Kelly appeared to have a great time with her celebrity friends at the glitzy ceremony.
She later tweeted a picture of herself drinking champers and eating cupcakes with Miley Cyrus - who turned 21 yesterday.
Kelly commented: "Celebrating @mileycyrus 21st birthday backstage at the #AMAS! Thank god she is finally legal!"
