Meghan Markle and Prince Harry are due to make an appearance at Global Citizen Live, which is happening this weekend on Saturday 25 September.
The couple have come out in support of the organisation over previous months, but this time they will be joining some of the world's biggest stars at Global Citizen Live.
The concert is being held in Central Park and the lineup includes stars such as Billie Eilish, Jennifer Lopez and Coldplay.
But what is Global Citizen and why are Meghan Markle and Prince Harry supporting the movement? Here's everything you need to know...
What is Global Citizen?
The organisation describes itself as a 'movement' of engaged people who aim to use 'their collective voice to end extreme poverty by 2030.'
The annual concert has been organised to help 'defend the planet and defeat poverty'.
Meghan and Harry will use their time on stage to ask the EU and G7 to immediately donate at least $1 Billion for global Covid-19 vaccines.
Their aim is to provide aid for countries who have been hit hardest by the pandemic.
Harry made his first appearance for the organisation back in May at the Global Citizen’s VAX Live: The Concert to Reunite the World..
During his talk, he spoke about his work raising funds amongst the private sector for the vaccine-sharing program, COVAX.
Saying: “The vaccine must be distributed to everyone everywhere.
"We cannot rest or truly recover until there is fair distribution to every corner of the world. The mission in front of us is one we cannot afford to fail out and that’s what tonight is about.
"The virus does not respect borders and access to the vaccine cannot be determined by geography. It must be accepted as a basic right for all and that is our starting point.”
