In a display of respect, Duchess Catherine curtsied to Her Majesty The Queen as she arrived to kick off an Easter church Service in Windsor on Sunday.
Passing her grandchildren on her way into St George’s Chapel, Kate elegantly slipped one leg behind the other in a swift bob while grandson William bowed his head with a loving smile on his face.
It's said the 35-year-old always greets Britain’s longest-reigning monarch with this gesture, however it’s not usually performed in the public eye as it only occurs during the first time they meet in the day.
While Prince Harry opted out of the family commitments to spend the day with girlfriend Meghan Markle in her Toronto home, his place was assumed by granddaughters Princess Beatrice and Princess Eugenie.
The sisters looked bright and summery in neutral hues as they chatted to Princess Anne’s daughter-in-law, Autumn Phillips.
But the title of best dressed undoubtedly fell to The Queen herself, who lit up the day of celebrations in perhaps one of her brightest ensembles yet.
In a turquoise coat and skirt, Elizabeth waved to royal onlookers before accepting a colourful bouquet from children in attendance.
Smiling as he watched on was husband Prince Philip, who looked to be in good spirits after falling ill earlier in the year.
Also in attendance was Prince Edward and his wife Sophie the Countess of Wessex who made a family day of the occasion by bringing along son James and daughter Lady Louise Windsor, 13.
The Queen's youngest granddaughter has grown to be a stunning young lady after stealing the hearts of many playing the role of flower girl at Wills and Kate's 2011 wedding.
It's been a busy time for the parents of Prince George and Princess Charlotte, but the family of four sure won't be slowing down anytime soon.
Next month, they'll attend Kate's sister Pippa's wedding to James Matthews, where both George and Charlotte have starring roles.
