Queen Elizabeth's 90th birthday portrait was one of the sweetest royal moments of the year. Captured by iconic photographer Annie Leibovitz, the Queen was joined by her five great - grandchildren, Prince George, Princess Charlotte, Isla and Savannah Phillips and Mia Tindall, along with her two youngest grandchildren, Viscount James Severn and Lady Louise Windsor.Cheeky Mia Tindall stole the show holding her great grandmother's handbag, with her dad, Mike Tindall saying: "It just turned out to be the right photo at the right time and it will be something we'll always cherish, I think."
