King Charles and David Beckham Reunite as Prince Harry and Brooklyn Connect amid Strain

As King Charles and David Beckham stepped out for a spring royal tradition at the Chelsea Flower Show, another high-profile meet-up had unfolded across the Atlantic — one involving their sons.

On May 19, the King and his wife, Queen Camilla, made a festive appearance at the Royal Horticultural Society’s Chelsea Flower Show in London, taking in vibrant garden displays and honoring their beloved dogs with a visit to the RHS and BBC Radio 2 dog garden. The garden even featured the names of the couple’s cherished pets, including Camilla’s late dog Beth and new puppy Moley.

Among the show’s highlights was a new flower dedicated to Kate Middleton. “Catherine’s Rose,” with its coral-pink petals and fragrant hints of Turkish Delight and mango, was created to honor the Princess of Wales’ advocacy for the healing power of nature, with proceeds supporting The Royal Marsden Cancer Charity — where she previously underwent treatment for cancer.

Also at the flower show (for the first time) was Beckham, who is teaming up with Charles’ King’s Foundation (of which he is an ambassador) on a new campaign to inspire young people into careers in horticulture,

They met up at the Highgrove shop stand and Beckham, who was wearing a new rose named in the King’s honor, and Charles were seen sharing a warm reunion — a moment underscored by another notable development thousands of miles away.

PEOPLE previously confirmed that Prince Harry and Meghan Markle recently joined Brooklyn Beckham and Nicola Peltz at a private dinner in Montecito, California. The evening took place at the home of Paramount CEO Brian Robbins and his wife Tracy Robbins — close friends of the Duke and Duchess of Sussex — and was not personally arranged by Harry and Meghan.

“Brooklyn and Nicola were invited prior to David’s numerous global birthday galas, so the timing is pure coincidence,” a source tells PEOPLE. “While it was an intimate gathering, there were several additional guests, including VIPs and film executives. Brooklyn and Nicola had a wonderful time and found Harry and Meghan to be particularly kind, caring and generous.”

The dinner comes amid ongoing family strains for both father-son duos. Brooklyn and Nicola were notably absent from David Beckham’s 50th birthday celebration earlier this month, despite being invited. “The relationship is definitely not beyond repair,” the insider added. “They love and are always there for him. They’re just hurt and disappointed that he’s now playing no part in family life.”

Meanwhile, Prince Harry and King Charles remain estranged. In a candid May 2 interview with the BBC, Harry revealed that his father “won’t speak” to him and admitted he’s unsure “how long [his father] has” as Charles continues cancer treatment. Still, he expressed hope for reconciliation: “I would love reconciliation with my family. There’s no point in continuing to fight anymore.”

Charles’ outing on Monday honored the 111-year-old festival of all things horticultural, which was a favorite of Charles’ late mother Queen Elizabeth and is seen as a curtain-raiser for the spring and early summer season that includes Royal Ascot horse racing meeting and garden parties at Buckingham Palace. This year ,there is expected to be more than 400 horticultural exhibits, which will be seen by 145,000 visitors over the week.

The dog garden, which celebrates the central part dogs play in many families’ lives, features grass areas for dogs to enjoy and a large tree providing shade. It contains paths made with bricks that are decorated with the names of dogs belonging to Radio 2 presenters and RHS ambassadors – including TV gardener Monty Don’s dog Ned, and those of Camilla’s adopted Jack Russell Terrier, Bluebell and that of her beloved dog Beth, which died last year. Camilla’s new puppy, Moley is also featured on the path along with the name of King Charles’ dog, Snuff.

Over the weekend, Buckingham Palace released a new portrait of Camilla with her dog Moley, who was adopted from Battersea Dogs & Cats Home. After the week-long flower show, the garden will live on at the rescue center which lies across the Thames from Chelsea.

Another garden visited by the royal couple, who were accompanied by Charles’ brother Prince Edward and his wife Sophie, Duchess of Edinburgh, and the Duchess of Gloucester, was The King’s Trust Garden: Seeding Success.

The Trust, which was formerly known as the Prince’s Trust as it was created by Charles when he was Prince of Wales in 1976, has helped more than one million young people since its formation.

The garden highlights the ability of seeds to adapt and flourish in hostile environments — mirroring the work of the Trust, which was set up by Charles in 1976 to help disadvantaged young people thrive and get a foot into business and employment, tries to do for those it supports.

Grass and perennials mix with low-growing shrubs in the garden, creating what the palace says is “an intimate, quiet space.” The garden will live on at Uxbridge College, West London, where it will be used, developed and maintained by young people enrolled on The King’s Trust programs, other students and the local community.

The royals also visited the Wildlife Trusts’ British Rainforest Garden, designed by Zoe Claymore. The garden of The Wildlife Trusts, of which The King is Patron, has been designed to capture some of the characteristics of the wild and wet woodlands that once covered much of the British west coast. The Wildlife Trusts has a longterm mission to bring the rainforests back to the British Isles, and the garden has been designed as a representation of this precious habitat, which now only covers about one percent of British land.

Another section of the show was the London Square Chelsea Pensioners Garden, designed by Dave Green and set to be based at the Royal Hospital Chelsea, home of the famous Chelsea Pensioners. The Royal Hospital is the site of the annual flower show.

Dave Green hopes to reflect the 300-year-old heritage of “a home for soldiers broken by age and war,” a statement said.

The central inspiration for the garden is inspired by the joining of hands, when Pensioners and their guests come together. Boundaries include native hedging and a brick wall that links to the architecture of the Royal Hospital Chelsea.
