Tuesday's event comes hours before the Duke and Duchess of Sussex are due to make a red carpet appearance at the Ripple of Hope Awards in New York.
Meghan and Harry will receive the Robert F. Kennedy Human Rights Award in honour of their "heroic" stance against racism within the royal family. The foundation is named after former President John F. Kennedy's younger brother, who was assassinated in 1968 during his presidential campaign.
Their new documentary is set to land on Thursday 8 December, and is called an "unprecedented and in-depth" documentary series.
The synopsis reads: "The Duke and Duchess of Sussex share the other side of their high-profile love story. Across six episodes, the series explores the clandestine days of their early courtship and the challenges that led to them feeling forced to step back from their full-time roles in the institution."
