Prince Harry was welcomed by huge crowds on Tuesday as he visited the New Jersey towns affected by Superstorm Sandy.
Amid the crowds, Harry focused one young admirer who had dressed up as a princess for her meeting with the royal.
The uncle-to-be once again demonstrated his easy way with children as he held the youngster's outstretched hand and spent time chatting with her.
Harry had specifically requested a visit to the areas affected by last year's Superstorm, which caused mass devastation and loss of life on the East Coast of America.
The Prince looked serious as he was guided around the picturesque waterfront towns Mantoloking and Seaside Heights by New Jersey's Governor, Chris Christie, who presented him with a "royal fleece" similar to the one the Governor wore after the Hurricane hit.
The royal viewed the ongoing construction projects being carried out and met with families who had lost their property to the costliest storm the U.S. has ever known.
Harry was impressed by the residents' community spirit and said, "Everyone is getting on with it. The Governor here has been absolutely fantastic.
"It's nice to see everyone out working together."
Harry later flew by helicopter to New York City where he joined Prime Minister David Cameron at an event to promote British trade.
The duo visited the Big Apple's Milk Studios after arriving on an iconic double-decker London bus. The appearance formed part of the 'Great' campaign, which looks to promote Britain as one of the best places to visit, live, work, and do business in.
Harry was following in the footsteps of his cousins Princesses Beatrice and Eugenie, who drove a Mini Cooper from Berlin's Brandenburg Gate to the British Embassy as part of a 'Great' PR drive earlier this year.
Harry's day ended with a game of baseball in the famous New York neighbourhood of Harlem. The royal was supporting the charity Project Coach, an initiative that provides youngsters with personalised coaching opportunities and works alongside the Prince's own Royal Foundation.
Harry got into the spirit of the sport by hitting a home run. Jolita Brettler, 9, was one of the children impressed by the royal's prowess.
"He hit that thing out, all of us were like 'wow!' Who thinks that a Prince is going to play baseball?" she said. "Princes are usually in castles or doing something important."
