The 4th annual Global Citizen Festival took place on New York's Central Park Great Lawn on Saturday, and the music festival was a total hit.

The star-studded event included Arianna Grande, who sang a sweet and soulful duet of her song “Just a Little Bit of Your Heart,” with Coldplay's Chris Martin and Ed Sheeran who graced the stage alongside Beyoncé for a rendition of "Drunk in Love."

But the audience was even more excited about one guest in particular—First Lady Michelle Obama.

Obama, always polished, was in head-to-toe black: a simple blouse and slacks with her hair in a sleek side-part. The First Lady appeared on stage immediately following Beyoncé's incredible high-energy performance and praised the Grammy winner, saying she was, "honored to follow a woman whom I admire and adore."

Then FLOTUS went on to official presidential business: she was on a mission to spread the word about a cause very important to her and related to the theme of GCF and a sect of the Let Girl's Learn Initiative—the 62 Million Girls Campaign.

"62 million girls are not in school. These are our girls. They deserve the same chances to get an education as my daughters and your daughters," she said and continued, "I see myself in these girls. I see my daughters in these girls. For me this is truly a moral issue."

She called for participation from the audience at large by tweeting pictures of themselves with the hashtag #62milliongirls and answering the question: What did I learn in school?
