Bad news for Britney Spears!  The pop star has been accused of putting on a boring show in Australia, but now her promoter is fighting back.

Spears took her Circus tour to Perth on Friday, and media reported fans walked out after just a few songs.

However Spears' tour promoter says those reports are inaccurate and says the singer is extremely upset over them.

He says it's well-known that part of Spears' concert is lip-synched, and that the show is all about putting on an incredible spectacle.
