The king and queen wrapped up their time in New York with a dinner at Christie’s in New York City for the Greater Together Reception which is held in partnership with the King's Trust.

Attending the dinner were cultural figures including Anna Wintour, Charlotte Tilbury, Donatella Versace, Edward Enninful, Iman, Karen Elson, Katherine Jenkins, Leo Woodall, Lionel Richie, Martha Stewart, Meghann Fahy, Nina Dobrev, Pat McGrath, Stella McCartney and Ralph Lauren, according to reporters who are traveling with the king and queen.

The King's Trust charity in America works with young people to develop employment training.

Ambassador Christian Turner, Lionel Richie and the king shared remarks at the event, according to a pool report.

Charles went from gardening with children to meeting with top CEOs Wednesday in New York City.

At an afternoon reception held on the 65th floor of Rockefeller Center, Charles met with leaders of companies including Bank of America, Blackstone, JP Morgan, Comcast, Citigroup and Alphabet.

The king shook hands with the business leaders and talked to them about their careers and how they’re investing in the U.K., according to reporters traveling with him.

Charles then went onto a bigger meeting with 50 more executives who snacked on canapes and ice tea and wine while they spoke with the king about their work in areas including technology, healthcare, financial services and more.

Camilla was joined by a star-studded lineup at a solo event held at the New York Public Library Wednesday.

Actress Sarah Jessica Parker, Vogue’s Anna Wintour, singer Katherine Jenkins and authors Min Jin Lee and Harlan Coben were among the luminaries who gathered with Camilla at an event to promote her charity, the Queen’s Reading Room, which celebrates the power of reading.

“The first Americans, I met in life were the characters I met in my treasured childhood novels,” Camilla said in her remarks, according to reporters traveling with the queen. “I knew even then, the books are best friends you can have, in good times and bad.”

She continued, “As many of us long suspected, books really are good for us. They also have a magic way of bringing people together with the ability to transcend any barrier."

After a series of formal events, Charles got to spend time outdoors with children Wednesday afternoon in New York.

The king, a known environmentalist, visited Harlem Grown, a nonprofit organization that helps teach kids about urban farming, sustainability, and nutrition, according to its website.

Charles was seen leaning over a fence to feed chickens alongside a group of kids during the visit.

King Charles has visited the United States 19 times before but today will mark his first state visit as a monarch.

Charles’ first trip to the U.S. was in 1970 when the 21-year-old Prince of Wales traveled with his sister Princess Anne and were guests of the Nixons.

Charles also traveled to Los Angeles in 1974 where he met and struck up a friendship with Barbra Streisand.

In 1985 Charles, accompanied by Princess Diana, met the Reagans at the White House. It was on this trip that Diana famously danced with John Travolta.

In 2005 Charles took Camilla to see the Bushes on their first official overseas trip since their marriage, and in 2015 the couple returned to the White House as guests of the Obamas.

This trip will have echoes of previous royal visits when Charles' mother, Queen Elizabeth II, visited the United States in July 1976 for the 200th anniversary of American independence. More recently, in 1991 Elizabeth became the first British monarch to address Congress.
