Harry will be in the Garden State in May to get a firsthand look at damage caused by Superstorm Sandy. The prince, an army officer who saw combat service in Afghanistan, is scheduled to be in the United States May 9-15 on a trip to raise money for U.S. and British troops.
Christie said Monday he will be with Harry for the day he is in New Jersey, the Asbury Park Press reported.
"If you trust me, all will be fine, because I'm going to spend ... during his entire trip, I will be with Prince Harry,'' Christie said on "Ask the Governor'' show on FM-101.5.
Harry got into trouble during his last U.S. trip when photographs showing him in the buff during a game of "strip billiards" at a Las Vegas hotel went viral on the Internet.
Christie said Harry has apologized for last year's incident.
"I certainly don't want to get all over the prince," Christie said. "I'm thrilled that he wants to come and see the destruction himself first hand and he wants to be helpful. And I'm going to be spending the entire day with Prince Harry.''
