It's been a minute since fans have enjoyed a glamorous royal wedding, but one of the lesser-known Windsors announced some exciting news over the weekend. On Sunday, June 8, Lady Marina Windsor—granddaughter of the Duke and Duchess of Kent and third cousin to Prince William and Prince Harry—shared she was engaged to her boyfriend of two years, Nico Macauley.

"Very happy! 💞🎊🌸" Lady Marina, 32, captioned a carousel of photos showing off her new engagement ring. The princess-cut stone appears to be an onyx or deep garnet gem and is surrounded by diamonds, and Marina proudly held it up to the camera in two selfies with her new fiancé.

The couple has rarely been spotted together at official events but Macauley makes frequent appearances on his bride-to-be's Instagram account. Per LinkedIn, Macauley is a graduate of Newcastle University and serves as an account executive at cloud security company Zscaler, while Lady Marina is a philanthropic executive at The Big Give.
