It’s official: eBay has gone Hollywood. Jessica Simpson found the cowboy boots she wears in her ”These Boots Are Made for Walkin”’ video on the online auction site (for about $100), Katie Holmes bid on antique books in her trailer while shooting Batman Begins, and eBay pops up as a plot point in The 40 Year-Old Virgin. Why so popular? ”Celebrities want that special something that no other celeb has,” says eBay spokesperson Constance White. And God knows they don’t have enough of that.
