Jeannette Walls of MSNBC.com reports that Vera Wang is furious over Jennifer Lopez and Ben Affleck cancelling their wedding, according to a source. “Jennifer got Vera Wang to make her an incredibly gorgeous dress, and really ran Vera’s staff ragged,” an insider told Walls. “The gown is worth at least $15,000 to $20,000, but Jennifer insisted she get it for free. The idea was that the publicity from the wedding would more than pay for the cost. Now, no wedding, and no publicity.” No comment from either party was given.
