On Friday the Prince began his royal engagements, (this trip is actually his first official visit overseas) by heading to Ground Zero, where he laid a wreath and kept a minute’s silence before meeting families who had lost loved ones on 9/11.

Then yesterday Harry joined youngsters at Harlem Children’s Zone, which works with 8,000 disadvantaged children, in an energetic obstacle course, after which he took part in a charity polo match, which attracted a very star-studded crowd indeed.

Celebrities who turned up to watch the Prince included, Madonna, Marc Jacobs, Chloe Sevigny, and Kate Hudson.

But it was all for a good cause of course; at the end of the day, Harry and the rest of the polo team had helped to raise £100,000 for the American Friends of Sentebale, the US arm of his charity - which cares for Aids orphans in Lesotho. That’s pretty impressive work for his first official Royal overseas visit we think you’ll agree…
