A dose of flu means that two dates have been rescheduled...

BRITNEY SPEARS has postponed the start of her US tour due to illness.

Spears was due to start her forthcoming tour of North America in Miami on October 26, in support of her forthcoming, eponymous new album. However, MTV news reports that the teenage star has been diagnosed with flu and ordered by doctors to rest for seven days. As a result, the tour will now start at the Washington MCI Center on October 31 .

Scheduled shows in Miami (October 26) and Tampa (28) have been rearranged for December.

Spears released her new single, ‘I’m A Slave 4 U’ last Monday (October 15), and it is expected to be a Top Five entry in the UK singles charts this coming Sunday (October 21).
