Is the "Real" Duchess of Cambridge on this Royalty section of Answers? Could it be someone else using the name?

Could it be some poor sap is using the Duchess' names falsely, as a way to get attention? Someone with the Duchess of Cambridge name, and a profile picture of the former Ms. Middleton on wedding day, answered one of my questions! I want to know if it is the Real Duchess? What a grand privilege to have had an answer by the Duchess-IF this is the right one!
