George Clooney and his wife Amal attended the King's Trust celebration at the Royal Albert Hall on Monday night with Benedict Cumberbatch and Sir Idris Elba.
Rita Ora, Rolling Stones star Ronnie Wood and Sir Rod Stewart were among performers marking five decades of the organisation.
The King founded the trust in 1976 when he was the Prince of Wales with the aim to end youth unemployment.
During an interval Sir Rod appeared to congratulate the King on his visit to America.
He told him: "May I say, well done in the Americas. You were superb, absolutely superb, put that little ratbag in his place."
King Charles had arrived in the royal box as singer Ruby Turner and the audience sang the National Anthem before the show, which was hosted by Ant and Dec.
Other musicians at the celebration included Jools Holland, Craig David and Anne-Marie.
The ceremony featured awards given to young people helped by the charity who went on to great achievements.
They included asylum seeker Musa, who won the L'Oreal Paris Rising Star Award.
Musa had fled Sudan and arrived in Glasgow before being referred to The King's Trust Explore programme.
It helped him meet new people and now he works for a landscaping company in the city.
Naina grew up in rural India and had withdrawn from school, left to study alone at night.
The trust's partnership with the Aga Khan Foundation supported her to rejoin school, and she now provides training to other girls and encourages them to stay in education.
She received the Amal Clooney Woman's Empowerment award at the ceremony.
Brandon, from Chorley, Lancashire, was given the Homesense Young Achiever Award.
He struggled with his mental health after being unemployed for a long time but the trust helped him back into work.
A Business Administration programme was the springboard for a work placement which led to a career with the same company.
Charles and Camilla switched places with Ant and Dec at the end of the night as the royals came out on stage while the TV duo were in the royal box.
The King joked: "I've always wondered whether someone would put Ant and Dec back in their box."
He then thanked staff and everyone involved in the King's Trust, adding he hoped it would go on for "as long as possible".
The King's Trust was founded in 1976 to help young people gain skills needed to find work.
Its courses for those aged between 11 and 30 is estimated to have assisted 1.3 million people.
