Princess of pop Britney Spears has told concert-goers she's sorry they were kept waiting for 30 minutes after smoky conditions brought a halt to one of her shows in the Canadian city of Vancouver.
A spokesperson posted an apology on the singer's site which explained the "brief pause" which took place on Wednesday because "crew members above the stage became ill due to a ventilation issue".
Britney kicked off her Circus tour of North America and the UK on March 3. At the moment the tour is scheduled to end in Manchester on June 17, but the 27-year-old singer's team are considering expanding it to include Australia and Europe.
