Dame Helen Mirren has paid a fitting tribute to the Queen, describing her as the "epitome of nobility" in her heartfelt post.
The actress, 77, played the role of Her Majesty both on the silver screen and on stage and told her one million followers on Instagram that she was "proud to be an Elizabethan".
Many of the Oscar-winning star's followers took to the comments section to share their own messages of condolence.
