Prince Harry and Meghan, Duchess of Sussex are gearing up for their first in-person event since welcoming daughter Lilibet.
The royal duo are set to attend the Global Citizen Live event at Central Park in New York City on Saturday, September 25.
An official statement from Global Citizen read: "Prince Harry and Meghan will join the 24-hour global broadcast event live from the Great Lawn in New York City's Central Park, to continue their urgent work with world leaders in the pursuit of global vaccine equity to end the COVID-19 pandemic for everyone, everywhere."
This will be the couple's first public outing in months, as both Harry and Meghan have taken time off since their daughter's birth in June.
Though it's unlikely either of their children – Archie, two, and Lilibet, three months – will make appearances, royal watchers are still eagerly awaiting their first glimpse of Lilibet.
Harry and Meghan are expected to speak at the event, which is calling on the world's wealthiest nations to share billions of COVID-19 vaccine doses with those most in need.
It's not the first time the couple have supported the push for vaccination equity either.
They were co-chairs of Global Citizen's VAX LIVE: The Concert to Reunite the World in May and Harry even attended the event, where he gave a bold speech.
"The virus does not respect borders, and access to the vaccine cannot be determined by geography," he told the audience in May.
"It must be accepted as a basic right for all and that is our starting point."
Meghan did not accompany him for that appearance as she was heavily pregnant with Lilibet at the time, but she has voiced her support for the cause in other ways.
She and Harry previously penned an open letter calling on pharmaceutical companies around the world to share COVID-19 vaccines with poorer nations.
"The COVID-19 pandemic has exacerbated health, social, and economic inequality globally," the couple wrote.
"The global vaccine rollout thus far further deepens these disparities, with the poorest and most marginalized populations most adversely impacted."
Since quitting royalty in 2020, the Duke and Duchess of Sussex have been living and working in the US, where they've supported a number of humanitarian and charitable causes.
In August they donated an undisclosed sum to support women and children fleeing Afghanistan after the Taliban's takeover of Kabul.
More recently, the couple were named among TIME Magazine's 100 most influential people of 2021 and even graced the publication's cover.
"It would be much safer to enjoy their good fortune and stay silent. That's not what Harry and Meghan do, or who they are," the outlet wrote of the royal duo.
"In a world where everyone has an opinion about people they don't know, the duke and duchess have compassion for the people they don't know.
"They don't just opine. They run toward the struggle."
