Paris Hilton claims cocaine purse is not hers -- but did she tweet a pic of it?

paris-hilton-purse-getty-lvpd.jpg Paris Hilton may just have been caught web-handed. Her big defense when she was arrested for cocaine possession Friday (Aug. 27) was that the purse containing the blow was not hers.

Except, as the Twitter moles at People have pointed out, Paris tweeted a picture of what appears to be the purse in question back on July 15, based on the purse captured in her arrest photos. She tweeted along with the pic, "Love My New Chanel Purse I got Today. :)."
