King Charles and Prince William appeared together at the Natural History Museum in a public show of unity ahead of the COP30 climate summit in Brazil. The outing was designed to reinforce the monarchy’s backing for environmental action and to build momentum for the Prince of Wales’s Earthshot Prize ceremony due to take place in Brazil.

The optics, however, were tested online after a past video of model and TV host Heidi Klum resurfaced. In that clip, recorded around last year’s Earthshot ceremony, Klum casually admitted she knew little about the initiative and had attended after being invited by William’s team. The snippet reignited old debates about the prize’s reliance on celebrity star power.

Critics on social media argued that relying on famous faces risked diluting the Earthshot mission, framing the project as public relations rather than substance. Royal watchers who are sympathetic to Prince Harry and Meghan Markle used the moment to question Kensington Palace’s approach and priorities.

Supporters of the Prince of Wales countered that Earthshot has seeded real-world projects and attracted global partners, insisting that celebrity involvement amplifies causes and funding. Despite the chatter, aides are pressing ahead with preparations for the Brazil awards, presenting the initiative as a flagship royal effort to scale climate solutions.
