George Clooney and wife Amal were in good spirits on Wednesday as they arrived hand in hand at the King's Trust Award at Buckingham Palace. 

The Hollywood icon, 64, and his human rights lawyer wife, 47, dressed to impress as they attended the reception celebrating the winners at the palace. 

The actor was back to his grey locks, much to the delight of his wife who George previously said 'hated' the freshly brown dyed locks he had for his latest Broadway show.  

The couple couldn't contain their smile as King Charles III chatted away to the couple before greeting guests. 

The Clooneys have long supported the work of The King's Trust, formerly known as The Prince's Trust. 

The Amal Clooney Women's Empowerment Award, launched in 2019 with the Trust, celebrates the achievements of inspirational female youngsters around the world. 

 The actor cut a dapper figure in a grey suit which he teamed with a matching open collar shirt. 

Meanwhile Amal made sure to turn heads in a black off the shoulder gown which she teamed with towering heels and a gold clutch.  

Amal posed in a snap with Alice Ngitira who was nominated for a King's Trust award for her work with young people and her dedication to overcoming mental health challenges. 

She was recognised for her crafting workshops which she developed when she was hospitalised. 

Barrister Amal is known for her work defending women's and human rights issues across the world, while her and George co-founded the Clooney Foundation for Justice back in 2016. 

The non-profit organisation focuses on defending human rights, particularly free speech and women's rights, by providing free legal aid and advocating for policy changes.

The King met with the winners of the eight UK categories during the day as well as the three winners of the three global categories ahead of the awards ceremony, which will be held at the Royal Festival Hall on Thursday.

Also mingling with the royal was make-up mogul Charlotte Tilbury, who looked to enjoy a spirited chat with the royal, and national treasure Dame Joanna Lumley.

Actor Joseph Fiennes, presenter Declan Donnelly, Fearne Cotton, Rosie Huntingdon-Whiteley and members of girl group the Sugababes were also present at the glitzy reception. 

The star-studded reception greeted a beaming Charles after he had appeared to enjoy the performance by The Herds, a group of life-sized animal puppets operated by artists at the event earlier this afternoon.

The contraptions slowly made their way down a staircase in the Grand Hall before the Gorilla moved towards the King and held out its arm.

The public art group are travelling from the Congo Basin to the Artic Circle, to raise awareness of humanity's bond with the natural world and the impact of climate change.

They have just arrived in London ahead of a series of performances at landmarks throughout the capital this weekend.
