"In school I learnt how to speak up for myself," says Michelle Obama.
"But without access to education 62million girls worldwide will never have that chance."
The FLotus is raising awareness over the lack of education for girls across the globe with the initiative #62MillionGirls.
On Saturday she took to the stage at the 2015 Global Citizen Festival in Central Park alongside Beyonce, Ed Sheeran and Nobel Peace Prize winner Malala Yousafzai.
Following a warm embrace with Beyonce, Obama addressed the crowd, urging them to join the campaign.
Right now 62million girls are not in school. And what's important to know is that these are our girls. They deserve the same chances to get an education as my daughters and your daughters and all of our children.
Make no mistake about it, giving them the chance is at the core of our work to end global poverty. It's the only way to ensure that these girls can fulfil their potential, provide for their families and contribute fully to their countries.
In a powerful call to action she announced, "If you haven't done so already here's what I need you to do. I need all of you to join our 62milliongirls campaign right now."
Obama called upon everyone in the audience, everyone watching the video to Tweet or Instagram a selfie and answer the question "what did I learn in school?" with the hashtag #62MillionGirls.
