New photos showing the Queen with her two youngest granchildren and all five of her great-grandchildren.
Standing beside the Queen in the family portrait are the Earl and Countess of Wessex’s children - James, Viscount Severn, eight, who has his hands in his pockets, and Lady Louise Windsor.
Lady Louise, who was one of the Duke and Duchess of Cambridge’s bridesmaids, is now 12 and towers above her younger relatives - earlier this week she was photographed in her Guide uniform openign the newly-refurbished Guiding HQ in London with her mother.
Captured by celebrity photographer Annie Leibovitz, the sovereign - in the tradition of royal portraiture - holds her youngest great-grandchild Princess Charlotte in her arms.
Also appearing in the touching image is two-year-old Prince George, as well as Zara Phillips’s two-year-old daughter Mia Tindall, who is proudly holding the Queen’s famous black handbag, and Peter Phillips’s daughters Savannah, five, and three-year-old Isla.
The photograph of the monarch, who is known as Gan Gan to George and Charlotte, was taken in the Green Drawing Room, part of the Windsor Castle’s semi-State apartments just after Easter.
Charlotte, 11 months, has a pink bow clip in her hair. She is dressed in a floral dress, pale pink tights and cardigan and appears to be holding a plastic toy horse, while perched on the lap of the Queen.
The image is one of three taken by Leibovitz to celebrate the head of state’s 90th birthday.
The Queen is also pictured in an informal shot in the white drawing room at Windsor with her only daughter the Princess Royal.
Anne, in a polo neck, shirt and jumper, sits close to her mother on a sofa, her arm resting behind the royal matriarch.
The third picture captures the Queen walking in the private grounds of Windsor Castle.
The Queen is seen on steps at the rear of the East Terrace and East Garden with her four dogs, her corgis Willow and Holly and dorgis Vulcan and Candy.
A relaxed-looking monarch has one had in her pale blue coat pocket as she prepares to ascend, while the dogs wait at various points on the stone steps.
Tonight beacons will blaze across the skies as communities gather to mark the occasion.
