Mere hours after the death of Queen Elizabeth II brought the world to a standstill Thursday (Sept 8), the queen's honoured pop culture figures Elton John, Helen Mirren and Mick Jagger shared their grief on social media.

The queen, who was Britain's longest-reigning monarch, died at her summer residence in Scotland on Thursday morning. She was 96.
