PRINCE Charles paid an emotional tribute to "Your Majesty, Mummy" during the star-studded Party at the Palace concert.
The Prince of Wales poured his heart out as he hailed the Queen for being with Brits "in our difficult times".
Millions of viewers watching from home were deeply moved as he said: "You have met us and talked with us.
"You laugh and cry with us and, most importantly, you have been there for us."
Directly addressing the monarch as "Your Majesty, Mummy", he said: "The scale of this evening’s celebration – and the outpouring of warmth and affection over this whole Jubilee weekend – is our way of saying thank you – from your family, the country, the Commonwealth, in fact the whole world.
"On behalf of us all, I wanted to pay my own tribute to your lifetime of selfless service.
"Your family now spans four generations. You are our Head of State. And you are also our mother."
And he said the Queen's "strength and stay" - her late husband Philip, who died last year - is "much missed".
"I am sure he's here in spirit," Charles said.
"My papa would have enjoyed the show and joined us wholeheartedly in celebrating all you continue to do for your country and your people."

He spoke to the crowd minutes after his son, the Duke of Cambridge, took to the stage to speak about the Queen's service.
William joked the venue had "turned into an IMAX screen" as performers including Queen and Rod Stewart entertained the audience.
And he used the speech to talk about the environment, telling of his pride in father Charles and grandfather Philip for their work.
"While no one’s grandmother thanks them for talking about their age, my own grandmother has been alive for nearly a century," he said.
"In that time, mankind has benefited from unimaginable technological developments and scientific breakthroughs."
"And although those breakthroughs have increased our awareness of the impact humans have on our world, our planet has become more fragile.
"Today, in 2022 – as the Queen celebrates her Platinum Jubilee – the pressing need to protect and restore our planet has never been more urgent."
However, he said he is an "optimist" - and said the Jubilee has provided great "joy" to Brits.
William was accompanied to the concert by wife Kate, who stunned in white, and the couple's eldest children Charlotte and George.
The family were seen laughing and joking together as they took their seats for the glitzy do at Buckingham Palace.

Hundreds of thousands of people lined The Mall to celebrate on Saturday evening.
There were huge cheers as the Cambridges arrived, hours after a royal visit to Wales with their two oldest children.
The Queen did not attend the festivities - although she recorded a hilarious clip with Paddington Bear, which was screened before the performances began.
In the skit, the pair - both much-loved British institutions - met for a chaotic cream tea.
Her Majesty revealed she shares Paddington's love of marmalade sandwiches and keeps an emergency stash in her trademark handbag.
The Queen watched performances from world-famous artists including Sir Elton John and Diana Ross from the comfort of her home on Saturday night.
But she was well represented by her family, many of whom appeared to be in great spirits as they took their seats.
Princess Charlotte, who stole the show on Saturday as she pretended to conduct a band on her visit to Wales, was spotted waving a Union flag.
