Ed Sheeran looks in good spirits as he supports his friend James Blunt at the premiere of his new documentary film One Brit Wonder

Ed Sheeran supported his friend James Blunt at the British premiere of James Blunt: One Brit Wonder at Picturehouse Central in London on Wednesday evening.

The Perfect hitmaker, 32, looked in good spirits as he posed with an arm around the musician, 49.

Ed cut a casual figure in a black jacket and white T-shirt as he made a rare public appearance at the event.

He completed his look with dark trousers and pink trainers as he was pictured with James and his wife Sofia, 40.

James' new documentary, One Brit Wonder, follows the soldier turned music star on his 2022 Greatest Hit Tour, giving viewers access to all parts of the series of shows in Europe.

The film will also look back at the artist's backstory, from witnessing the Kosovo War, recording the best-selling album of the 1990s and the iconic tweeting he is now known for.

Also present at the event were Princess Beatrice and her husband Edoardo Mapelli Mozzi, who enjoyed a night out.

It comes after Ed surprised fans when he jumped on stage and performed an impromptu duet with James at Princess Eugenie's anti-slavery charity gala last Wednesday.

The star-studded evening saw a host of royal and famous faces gather at London's Battersea Arts Center for The Anti Slavery Collective's inaugural Winter Gala.

Ed asked James five minutes before his set if he could sing his biggest hit You're Beautiful with him, as he knows his debut album Back To Bedlam by heart.

Ed introduced himself and said, “So we've never practiced this, never played it. James goes on the strength I know, Back to Bedlam, from front to back.'

James and Ed then began sharing and harmonizing lyrics during the impressive performance.

A source told MailOnline: 'Ed asked James five minutes before he went on and announced James on stage saying Back To Bedlam was an album he knew.

“And then they sang the song together from beginning to end.”

The insider said the pair were heading to famous hotspot Chiltern Firehouse to continue their evening.

Ahead of the event, Princess Eugenie, 33, praised Ed for his involvement, saying: 'It's the most insane thing. Ed is a game changer and a generational entertainer, so I absolutely can't get over him coming.

“He's also one of the nicest people, so I'm really honored and really grateful to have him here and helping us with the mission of The Anti-Slavery Collective.”

Eugenie, the Duke and Duchess of York's second child, said she was motivated to set up the charity, which aims to end modern slavery through the humanitarian work of her mother, Sarah Ferguson.

“My mother does a lot of charity work and has always raised my sister and I to give back,” Princess Eugenie said.

The Royal, who now lives in Portugal with her husband Jack Brooksbank and their two sons, said a trip to Calcutta with her mother and Julia in 2012 sowed the seeds of the Anti-Slavery Collective.

“We went to Calcutta to visit Aloka Mitra, who founded the Women's Interlink Foundation,” she recalls.

“Aloka is an amazing woman who has rescued girls from the streets, housed them and taught them how to print on fabric.

'On that trip to India, Jules and I were so shocked by what we had discovered about modern slavery that when we returned to Britain we learned as much as we could about it, meeting anyone who would listen to us, a safe haven visited. homes and spoke to survivors.”

The charity's mission is to raise awareness of the 50 million people around the world currently trapped in modern slavery.

'I was 21 when I first heard about modern slavery. I don't want people to reach the same age without being educated about reality,” the Royal said.

Ed had an infamous encounter with Princess Eugenie's sister, Princess Beatrice, who accidentally slit his cheek with a ceremonial sword while jokingly 'knighting' James Blunt at a dinner party in 2016.

The musician always refused to name Royal, but his manager, Stuart Camp, eventually confirmed that it was the princess who had wielded the sword, calling her an “idiot.”

One Brit Wonder hits cinemas on Wednesday 6 December and will be followed by a live concert. Tickets from jamesblunt.film.
