The Duchess of Cambridge, Kate Middleton, visited Bletchley Park "spy school" on Wednesday where she revealed a Middleton family secret. Bear with us...
The young royal took a trip to Britain's Government Code and Cypher School in Buckinghamshire, where her grandmother, Valerie Glassborow, once work as an intelligence officer AKA a spy!
The 32-year-old heard all about the role her dad's mum played at the once top secret location, chatting to veteran Lady Marion Body who worked with Valerie during the Second World War.
True to form the Duchess recycled a nautical look we first saw her in back in 2011. Frugal fashion is her thing after all.
The daughter of a banker, Valerie married the duchess' grandfather Peter Middleton 1946 and had four children, including Kate's dad Michael.
Kate's visit comes just days after she, Prince William and baby Prince George celebrated their very first Father's Day together.
While William took part in a charity polo match at Cirencester Polo Club in Gloucestershire, Kate and George cheered on daddy from the sidelines.
The royal pair were seen watching as William and his brother Harry competed in the annual Jerudong Trophy polo match. However, from the looks of things football - not polo - could well be Prince George's favourite sport.
The 11-month-old didn't seem very interested in the game at hand and seemed more keen for a kick about with mum Kate.
Dressed in a white polo shirt teamed with red and white striped dungarees and black shoes, George took a swipe at his football while Kate held his hand to help steady him.
While this is the first time we've seen George on his feet, the Duchess last week revealed he'd already started walking independently.
