Eagle-eyed royal fans have commented on how tall Prince George is - taking after the famous stature of his father and grandmother.
The future king, 10, joined his sister Charlotte, eight, and brother Louis, five, at his mother Kate'S Together at Christmas carol concert on Friday evening at Westminster Abbey.
Fans noticed how the young heir is shooting up in height, reaching to the shoulders of his mother Kate, the Princess of Wales, who stand a little over 5'7.
The Prince of Wales himself is over 6'2. He is thought to inherit his height from his mother Princess Diana, who stood at 5'8 and a half.
Royal fans on X, formerly Twitter, observed Prince George's height, with one saying: 'My goodness he's so tall.'

As they walked into the Abbey's forecourt the royal children paused for a moment to post Christmas cards, in a special postbox, containing messages for children who might be struggling this Christmas, something open to all youngsters attending.
The young royals - George, 10, Charlotte, eight, and five-year-old Louis - were all smartly dressed while their mother wore a Chris Kerr coat.
Before the concert started Kate met celebrities in the Abbey's stunning 16th century Lady Chapel, and chatting to Broadbent expressed her appreciation at him agreeing to read an extract from Letters From Father Christmas by Lord Of The Rings author JRR Tolkien.

Once inside, Kate stole the show as she led the royal family and high-fived and spoke with children who have gone 'above and beyond' for charity.

His mother Kimberley Burrow said afterwards: 'She said she'd heard about what he's done and he's doing a fantastic job, and hopes what he's doing will inspire other children to do amazing things.'
The princess was joined at her annual Christmas carol service by Prince William and children Prince George, Princess Charlotte and Prince Louis.
