The portrait, taken by Ranald Mackechnie and released on Friday, shows the British monarch along with Prince George, 6, Prince William, 37, and Prince Charles, 71, in the Throne Room of Buckingham Palace.
According to People magazine, it was taken just before the Queen's annual Christmas luncheon on Dec. 18.
A statement from the royal family's official social media accounts, which shared the image, read: "To mark the start of a new decade, a portrait has been released of Her Majesty The Queen and Their Royal Highnesses The Prince of Wales, The Duke of Cambridge and Prince George. The portrait was taken by Ranald Mackechnie in the Throne Room at Buckingham Palace."
This is the second time a portrait featuring the Queen and the next three in line to the throne has been published.
The first portrait was released in April 2016. It marked the Queen's 90th birthday.
