Prince William talks about helicopter controversy

During a visit to a community center in Penygraig, Wales, William told Mildred Francis, 82, "I'm working on my license. I'm trying to do as much flying as I can." Then he added with a smile, "But I've been accused of wasting money – joyriding."

"He said he's got into a bit of trouble for flying," Francis told reporters, "but he was very nice about it."

Last month, William was called a "show off" when he landed a chopper in a field behind girlfriend Kate Middleton's family home, PEOPLE reports.
