The royals’ trip the U.S. is now underway, as the Duchess of Cambridge arrived in Harlem, New York on Monday.

She spent about an hour inside the Northside Center for Child Development and even shook some lucky kids’ hands outside.

One of the administrators, Rose Ann Harris, told USA Today, "They thought she was the princess from Frozen.”

One of the well wishers waiting to catch a glimpse of the royal outside, Juliette Mace, said, "I don't remember Diana but I read a lot about her, and I think Kate is the new Diana. She's the most important of the royals. She's modern, she's beautiful, she's a princess, she's living every girl's dream of marrying a prince."

Kate then attended a lunch hosted by British Consul Danny Lopez at his New York City home, which NBC News’ Deborah Turness and actor Matthew Rhys also attended.

Meanwhile, her husband, Prince William, made a visit to the White House to speak with President Obama.

Although they separated today, they will reunite later this evening to watch a basketball game in Brooklyn.
