Kate Middleton, the Princess of Wales, has ended speculation about her whereabouts by announcing in a video message that she is undergoing chemotherapy for cancer. However, there are conspiracy theories circulating online that claim her video may be an AI-enabled deepfake. These theories question the authenticity of the video, pointing out elements like the lack of movement in the background and the absence of a dimple on her cheek. Despite these claims, they have not been officially verified.

Kate has received support from her family, including Prince Charles, Prince Harry, and Meghan Markle, as well as from British Prime Minister Rishi Sunak and US President Joe Biden. Kate expressed her gratitude for the public's support and emphasized the importance of talking to her children about her diagnosis before making it public. Rumors of an affair between Prince William and Sarah Rose Hanbury have also emerged during Kate's absence, but Rose Hanbury denies these allegations. In addition, controversy arose over a photograph of Kate and her children being edited or generated by AI, leading to its retraction by major news outlets.
