They had seemed to put rumors of a feud to rest, but new reports are indicating that Kensington Palace may have stepped in and intervened when it comes to a particular incident that has threatened to erupt between Kate Middleton and her in-laws, Meghan Markle and Prince Harry.

According to Express UK, the palace intervened when it came to the two different gardens that are being supported by the various members of the royal family at the Chelsea Flower Show. While the Duchess of Cambridge co-created a garden with the Royal Horticultural Society that highlights the benefits of a natural world for well-being, the Duke and Duchess of Sussex have lent their support to a garden showcasing African climate change, which is being presented by one of their chosen charities, Camfed. That display, which is set to feature a breeze-brick schoolhouse, crops, solar panels and a smart irrigation system, allegedly threatened to “overshadow” Middleton’s design, leading to Kensington Palace intervening on her behalf to make sure focus isn’t pulled from her own work.

Camfed was reportedly told they could not use a photo of Prince Harry surrounded by some of their organization’s alumni in order to publicize the garden, while the RHS website about their garden prominently features Middleton in photos.

“It is because the Duchess of Cambridge is co-designing a garden, so we can’t use the photo,” a source from Camfed told Express. “The palace is worried about mixed messaging.”

This isn’t the first time the discussion about the two dueling gardens potentially causing a feud has been raised. Back in March, it was reported that Middleton could be “humiliated” by the fact that her sister-in-law and brother-in-law were publicly backing a garden design that wasn’t hers.

“If I was Kate, I’d be humiliated they went down this route,” Julia Miller, host of Vanity Fair’s “In the Limelight,” said at the time. “I would be angry they hadn’t swapped notes before.”
