LONDON – Two Australian radio disc jockeys apologized Wednesday after impersonating Queen Elizabeth II and Prince Charles in a prank call and getting a London hospital to tell them all about Kate Middleton’s condition.

The King Edward VII hospital in London acknowledged that the Australian radio station made the hoax call to the hospital in the early hours Tuesday – 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.
