But Gladiator star Crowe said during a radio interview that he won’t be among the A-list crowd and suggested that it was “possibly based on the last time I was introduced to royalty”.
Discussing what happened the last time he met members of the royal family, he said on Triple M Breakfast Brisbane that the whole “your highness thing” wasn’t really in his nature.
He said: "You know, the equerry (an officer of the British royal household who assists members of the royal family) comes and talks to you and they go, ‘Listen, when you talk to the prince, you can refer to them as this and this and this and this. You know, don’t do this, don’t do that.’
“Yeah, like, OK mate.”
Crowe went on: “The thing is, it’s just not in my DNA to be deferential to that point.
“I’ll be respectful, I am very pleased to meet people, but the ‘your highness’ thing, it just doesn’t come out of mouth."
"It’s not in my DNA," said the screen star.
Crowe, 59, added of meeting the Princes: “I called both Harry and William 'mate’ and I thought the equerry was going to pass out!”
