CBS New York news anchor Rob Morrison accidentally called Prince William "the douche," instead of "the Duke" of Cambridge (video below) on Wednesday.
Morrison was promoting a report about Prince William and Duchess Kate's visit to Cambridge on Wednesday, reports the Daily Mail.
Morrison said: "Also the reason why the latest royal visit was extra special for the douche- Duke, ha ha, and Duchess of Cambridge."
Prince William is descended from the son of George III who was named the Duke of Cambridge in 1801 by Queen Mary.
Prince William and Duchess Kate made the trip to Cambridge on Wednesday to open a hospital.
