Oh no! Janet Jackson is in hospital with a mystery illness. The singer “got suddenly ill” moments before she was about to go on stage for a concert and was rushed to Cedars-Sinai Medical Centre in Los Angeles. It's not the first sudden hospital trip for Janet – the same thing happened in March of this year, but at the time her representative insisted she was just suffering from the flu. This time round, no further information has, as yet, been released. The Rock Witchu tour is her first in seven years – we really hope the strain isn’t too much and she is back on her prancing, dancing feet in no time.
