The 27-year-old star failed to please at her Perth, Australia concert in front of 17 000 fans last Friday.
According to different sources, Spears was lip synching during the show for certain songs.
This morning, Spears’ manager defended his client in The Australian paper, stating that the singer was very upset with what critics had said. For Paul Dainty, the reports that Spears is not singing the songs is a total fabrication.
The Australian press claims that fans left the show after only three songs, disgusted by the singer’s performance.
Such criticism could not be more untimely, since the Perth performace was Spears’ first show of her 15-date concert series in Australia.
Britney Spears has been accused of lip synching in the past. Other stars have already admitted to using this trick, especially when they have to dance and sing at the same time.
