Taylor Swift's London gig came at a huge cost to fans and taxpayers.

Police records indicate that the pop superstar's sold-out concerts at London’s Wembley Stadium came with a huge $890,000 price tag. According to the latest report on The Sun, the Metropolitan Police shelled out the big bucks on security for the pop superstar's eight shows. This is now said to be among the police's most expensive events in London last year.
