A New York fundraising dinner in aid of US supporters of Prince Harry's Royal Foundation has attracted the wealthy, famous and glamorous.
Harry found himself rubbing shoulders with the elite of American society and Prime Minister David Cameron at Manhattan's famous Four Seasons Restaurant.
The third-in-line to the throne proved a draw to Sean Lennon, son of Beatle John Lennon, The Voice judge will.i.am, writer John McInerney, who penned Bright Lights Big City, and his socialite and philanthropist wife Anne Hearst McInerney, the granddaughter of newspaper baron William Randolph Hearst.
The glitzy night was in aid of the American Friends of The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry.
Speaking about Harry, Sean Lennon said: "It's great that he is here. He seems to be really enjoying it. But it seems as if the whole city is running around trying to spot him, so I hope he doesn't think New York is always like this. He is well loved here."
And will.i.am said: "I am a fan of how Queen Elizabeth raised her children and how they have raised their children.
"I am a great admirer of Prince Charles and his charity work and I think it is incredible Harry has made it part of his legacy to carry this on. He doesn't have to do what he does, so I applaud him."
The Black Eyed Peas star and producer met the Prince after last year's Diamond Jubilee concert at which he performed.
He added: "He's a party prince, a soldier and a philanthropist. He's a regular guy. If Harry was a movie character he would be Iron Man.
"I grew up watching documentaries about the Royal Family so I am really pleased to be meeting him."
