Janet Jackson pulls more dates

Janet Jackson has postponed more concerts due to a mystery illness.

The 42-year-old singer was forced to cancel several shows after she was hospitalised last week and was due to her resume her 'Rock Witchu' tour in North Carolina on Saturday (04.10.08) but pulled out at the last minute.

Janet was reportedly keen to play the show and even arrived at the Greensboro Coliseum where it was due to take place, but was advised by a local doctor not to perform.

She informed concert organisers she was not well enough to play 90 minutes before she was due on stage.

Janet went on to cancel her Sunday show in Atlanta (05.10.08) and her concert in Fort Lauderdale tonight (06.10.08).

The shows will all be rescheduled for a later date. Although the nature of Janet's illness has not been officially confirmed, it has been rumoured she is suffering from vertigo.

This is the second time this year the star has received hospital treatment. In March, Janet checked into the Los Angeles' Cedar-Sinai Medical Center to be treated for flu symptoms after complaining of "shortness of breath".
