Martha Stewart is engaging in a smear campaign against Vampire Vineyards to bolster the sales of a Gallo wine label bearing her name, this according to a new federal lawsuit obtained by TMZ. According to the suit, Stewart's Gallo wine sales are less than one-half the wine sales of Vampire Vineyards. To catch up, the suit claims Stewart and her company, Omnimedia, are selling counterfeit Vampire Vineyards wine labels "to disparage and tarnish [Vampire's] wine brands by portraying a mock label of Vampire Vineyards affixed to cheap, non-descript wine and spirits products."
