"Behind closed doors, she's our grandmother, it's as simple as that," Contactmusic quoted Prince Harry as saying.

"As I learned from growing up, you don't mess with your grandmother ," William said.
Harry, 27, also joked with host Katie Couric that the Queen hadn't even requested his friendship on social networking website Facebook.
He replied to her humorous question: "No she hasn't. Why has she friended you?"
