The 21-year-old - who collapsed at the weekend, reportedly through exhaustion - has been ordered to rest for a week.
A source says, "She needs four days off. It's the start of a very busy time. The album release, two singles and a 10 arena tour are all on the way".
The band hope to reschedule the HARBORFEST gig for "some time in the next couple of weeks" - but Natasha's illness isn't expected to affect the release of their new single IF YOU COME TO ME, on Monday (27OCT03).
THE Rolling Stones, Santana and Westlife are also scheduled to appear at HarborFest - a month long (NOV03) event too raise money for victims of the severe acute respiratory syndrome that hit the far east earlier this year (03).22/10/2003 21:19
