Kate Middleton's Hospital Apologizes for Prank

The London hospital where Kate Middleton is recovering from acute morning sickness has apologized for a prank in which DJs from an Australian radio station called the hospital posing as Queen Elizabeth and Prince Charles and were able to obtain information about Kate's condition.

A statement issued by King Edward VII Hospital on Wednesday said it "deeply regrets" accepting the "hoax call," which came in early Tuesday morning and was transferred to a member of the facility's nursing staff.
