While North American fans may be no strangers to Britney Spears' lip-synching, audiences Down Under seem to have been caught off-guard by the recording artist's "mimed" performances. Poor reviews have dogged the pop princess as she completes her itinerary of shows across Australia, and fans are reportedly selling off unwanted tickets at rock bottom prices. One report found that "diamond-class" premium passes valued at $200 (AU) were being sold for as little as $32 (AU). Meanwhile, some regular tickets were being listed for as little as 99 cents. Ticket brokers expected to lose big on their tickets for the tour, which has ten more shows lined up through the end of the month.
