King Charles and David Beckham send clear message after Harry and Brooklyn's secret summit

has made a surprise appearance at , as he joins the King to tease an upcoming project with the King's Foundation, which will aim to encourage young people to consider careers in horticulture.

Wearing a new rose named in honour of the monarch in his buttonhole, the former England football captain agreed with Camilla that the bloom was "so beautiful" as they caught up outside the Highgrove stand at the annual garden showcase. The King's Rose is showing at Chelsea for the first time, with all sales going to support the King's Foundation.

The royal couple were greeted by Beckham and TV gardening guru Alan Titchmarsh towards the end of their annual visit to the show, with David telling the Queen: "Your Majesty, it's so nice to see you." As she gestured at his buttonhole, he said: "It's so beautiful, so beautiful, congratulations."

During their warm exchange, David appeared to thank the King for something, after the monarch asked: "You got it, didn't you?"

The footballer, who recently celebrated his 50th birthday, replied: "It was incredible, thank you, it was very kind."

And Camilla was heard to say, "Nice to see you again, glad you got the roses."

Beckham, who is an ambassador of the King's Foundation, met the King and Queen at the Highgrove Shop stand, where all proceeds go towards the work of the Foundation.

The former England Captain also met with fellow ambassador Alan Titchmarsh at the London Square Chelsea Pensioners Garden, where the work of King's Foundation furniture making alumni Lily Hitchcock and Hannah Evans was featured as the table centrepiece.

The royal meeting comes just days after it emerged and n amid their family row.

The Duchess of Sussex and Nicola found "common ground" after both were accused of wrecking their husbands' families, reported. Brooklyn failed to attend his father's high-profile 50th birthday celebrations earlier in the month.

The royal couple stood with David and Alan - both ambassadors for the King's Foundation - as the stand's shopfront was ceremonially unveiled with the opening of a theatre-style pair of Sanderson-designed curtains, reflecting a partnership between the interior design house and the King's Foundation.

The shop, adorned with floral displays created by Shane Connolly, the designer behind the flowers at the Coronation, is stocked with items for sale to raise funds for the charity, which celebrates its 35th anniversary this year.

It marked the first time the football legend had ever attended the world-famous showground, as he went to tease an upcoming King's Foundation campaign, in partnership with the RHS and championed by Beckham and Titchmarsh.

The project seeks to encourage young people to consider careers in horticulture, to protect our green spaces and natural environment for future generations.

A host of stars stepped out for the opening day of the Chelsea Flower Show today, with the likes of Myleene Klass, Nick Nowles and partner Katie, and Vanessa Feltz, enjoying the gardens in the spring sunshine.

Earlier, the Queen held a bouquet of 'The King's Rose' bred by David Austin Roses and sniffed the beautiful bloom of fuchsia petals and white stripes, while the King chatted with the leading rose-breeder at his stand inside the Great Marquee.

"Does it smell?" he asked as he leaned in to find out. "It does smell, it's a lovely musky fragrance," replied owner David.

Asked about the breeding process, the King was taken aback to hear the new rose was grown from one of 60,000 seedlings originally planted 12 years ago and developed by a team of 20 people.

"I must say, this is amazing," the King told him, gesturing to the stand, which is the largest ever for the family-run business.

Established in 1913, on the grounds of Royal Hospital Chelsea in London, the RHS Chelsea Flower Show has become one of the world's greatest showcases for horticultural excellence, attracting visitors and exhibitors from across the globe.

Since its beginning, the show has gone from strength to strength. It has grown from 244 exhibitors in 1913 to over 400 horticultural exhibits. Today, the show attracts 145,000 visitors each year.
