TWO Sydney radio disc jockeys have apologised after impersonating Queen Elizabeth II and Prince Charles in a prank call to get a London hospital to tell them all about Kate Middleton's condition.
The King Edward VII hospital in London confirmed the hoax call - and that the hospital fell for it.
The 30-year-old Duchess of Cambridge is pregnant and is being treated at the hospital for severe morning sickness.
A woman using the often-mimicked voice of Britain's monarch asked after the duchess' health - and was told by a nurse that Kate "hasn't had any retching with me and she's been sleeping on and off".
"She's sleeping at the moment and she has had an uneventful night. She's been given some fluids. She's stable at the moment," the kindly nurse informed the supposed queen and prince on the station's recording.
A dog yaps in the background during the recording while the alleged queen and prince talk about travelling to the hospital to check in on Kate.
"I would suggest that any time after 9 o'clock will be suitable to visit," the nurse said. "We'll be getting her freshened up."
2DayFM hosts Mel Greig and Michael Christian later apologisd for the hoax - along with their station.
"We were very surprised that our call was put through. We thought we'd be hung up on as soon as they heard our terrible accents," they said in a statement.
"We're very sorry if we've caused any issues and we're glad to hear that Kate is doing well."
The hospital is now reviewing its protocols.
