Washington, November 7 : Britney Spears could prompt the Australian government to come up with a new legislation after the star was criticised for miming during the debut performance of her Circus tour in the country.

The singer, who arrived Down Under for 15 sold-out shows across the continent, recently left fans disgruntled as she preferred to lip-synch and concentrate on theatrics and dancing during the live performance.

Disappointed devotees, some of whom splashed up to 1500 dollars to see the star, even began walking out after just three songs, according to reports.

The country's government was apparently mulling to enforce "new measures that would involve artists notifying fans on their tickets and advertisements if they intend to lip-sync", reports the Fox News.

Britney's tour manager, Steve Dixon, however, explained to Sydney's local newspaper The Daily Telegraph that miming was not a concern and that the crowd was drawn to the "pop spectacular experience."

A source close to Britney claimed she finds it hard to sing and dance at the same time.

The insider said: "Whenever Britney has to dance she lip syncs, but she really prefers to sing live when she doesn''t have to move around." (ANI)
