Another royal, a cousin of Prince William and Prince Harry, has gotten engaged and is gearing up to walk down the aisle. This isn’t just any cousin; she was once crowned the 'most beautiful royal' by Tatler, and the fashion world has backed that title. The stylish royal has strutted runways and fronted campaigns for major labels like Chanel, Alaïa, Penelope Chilvers, and Dolce & Gabbana, to name a few. And in true Windsor spirit, William and Harry’s cousin is also an outspoken environmental advocate, carrying forward the family’s long-standing passion for nature and sustainability.

Yes, we’re talking about none other than Lady Amelia Windsor, sister to Lady Marina Charlotte Windsor and daughter of King Charles’s second cousin, George Windsor, Earl of St Andrews, and Sylvana Tomaselli. Royal corridors are buzzing with excitement as, according to the Daily Mail, Amelia is officially engaged to her longtime boyfriend, Ollie Lewis. The duo had been dating since 2023 and is now reportedly ready to take the next step.

Lewis, a property developer, has been a steady presence by Amelia’s side, and it looks like their love story is heading straight toward a royal-adjacent happily-ever-after. The couple debuted their relationship at the Glastonbury Festival in 2023, and ever since, every year, the couple make it point to attend Wimbledon together. They have mostly preferred to keep their relationship very low-key, only making appearances during key events in the British social calendar.

The duo is usually spotted together in and around Hackney, where they live. Amelia is 44th in line of succession and is a third cousin to William and Harry. Just like her parents and sister, she too is a vocal ambassador for the 'No More Plastic' campaign. Amelia was last seen publicly at her grandmother’s funeral in September, where she and her sister kept a respectful distance from the cameras, avoiding any direct interaction with the media. She has yet to officially confirm her engagement, but anticipation is already building among royal watchers. With more than 100,000 Instagram followers, Amelia regularly uses her platform to highlight her modeling work, champion environmental causes, and stay connected with fans, many of whom had been hoping for the happy news.

Other than Amelia, it’s been a remarkably eventful year for the royal family. Princess Anne’s son, Peter Phillips, proposed to his longtime partner, Harriet Sperling, this summer, and on the very same day, Lady Eliza Spencer, Princess Diana’s niece, announced her engagement to her boyfriend, Channing Millard. The season of celebrations continued with sparkling rings for The Duke and Duchess of Kent's granddaughter, Lady Marina Windsor, and Charles's cousin and Prince Edward's goddaughter, Ella Mountbatten, for whom congratulations are also in order.
