Christina's one-off show cancelled amid bankruptcy wrangles

Christina Aguilera fans hoping to see the star perform live this summer have been dealt another blow - her one-off show has been cancelled.

The Dirrty singer abandoned her 28-date American tour - which was due to start in May - in April, citing doctors' orders to rest her voice as the reason.

But she provided a glimmer of hope when she signed up to do a private concert at an all-night dance party called Elements last Saturday in Pittsburgh, Pennsylvania.

But that show - which would have been Aguilera's first public performance since cancelling her tour - was also scrapped because the promoter filed for emergency bankruptcy at the last minute.

Though a total number of fans who bought tickets has not been disclosed, up to 20,000 of them paid between $75 (€61) and $150 (€122) for passes to the event.

Ticketholders now have to wait for bankruptcy court to review the promoter's assets and debts - which he has to provide within two weeks - before they can be considered claimants and get any refunds.

A lawyer representing the promoter says they're going to make every effort to pay back fans, but there's no guarantee.
