About
Former royal body double for Queen Elizabeth II. She acted as the Queen's stand-in for rehearsals for state dinners, royal engagements, and the State Opening of Parliament. She acted in this capacity for over 30 years and did not accept payment for her services.
Before Fame
While working at the BBC, a producer conveyed to her that the sun was in the Queen's eyes as she stood for a ceremony, and Slack offered to stand in her place. This led to her becoming the Queen's stand-in when needed.
Trivia
