Soundgarden frontman Chris Cornell and his wife, Vicky, are furious after discovering their wedding video was being offered on Craigslist as macabre “lost” footage of dead starlet Brittany Murphy, who was a maid of honor at their 2004 ceremony. Cornell claimed the video was stolen and he threatened to sue the popular site, which has removed the video from sale. A source said, “The video features behind-the-scenes wedding moments, many of Brittany Murphy.” He asked Craigslist to hand over details of the seller, arguing that it’s a federal crime because it’s considered stolen copyright. Cornell’s rep couldn’t be reached, and a Craigslist rep didn’t get back to us. Meanwhile, Cornell announced on New Year’s Eve via Twitter that he’s reuniting with Soundgarden: “The 12-year break is over & school is back in session . . . Knights of the Soundtable ride again!”
