Janet's stunning diva demand

Janet Jackson stunned Capital radio bosses by demanding chilled spring water from Fiji before she would agree to a studio interview.

The singer's assistants were dispatched to the station an hour before her breakfast show appearance with Johnny Vaughan to place the bottles in the fridge so they could be cooled to the precise temperature.

The water was then checked using a thermometer when Jackson arrived at the studio before she would drink it.

A source said: "It was simply unbelievable the lengths she went to for a cold glass of water.

"How anybody can tell the difference between a standard bottle of mineral water and some from a Fijian spring beggars belief."
