Brought on stage by this year's host, Alicia Keys, the former First Wife took the opportunity to introduce the show alongside some of the evening's biggest stars including Lady Gaga, J. Lo and Jada Pinkett Smith.
"From the Motown records I wore out on the south side", Obama said, as the audience erupted. "Music helps us share ourselves. Music shows us that all of it matters.every story within every voice, every note within every song".
First, Gaga spoke about her journey: "They said that I'm weird, that my look, my choices, my sound, that I wouldn't work but music told me not to listen to them.
I want to be the one that really just continues to reach out to the people that I love and admire and my friends, and just be able to create an unbelievable energy", she added. "It allows us to hear one another".
When it was Michelle's turn to speak, she was instantly drowned out by the crowd's cheers which went on so long she had to tell them to stop saying "alright, we've got a show to do".
A true diva, Ross owned the room and concluded her moment with an enthusiastic declaration: "Happy birthday to me!"
Obama is now touring to promote her memoir Becoming, which was released in the United States and in 28 languages around the world. But here's what I know: "Every voice we hear needs to be honored and respected".
One of the biggest musical events of the year, Grammy Awards are live right now and numerous worldwide sensations from across the globe have made it to the event.
Viewers on social media also cheered Obama's appearance. "Tonight we celebrate the greatness in each other, all of us, through music". Lady Gaga highlighted that many of her problems and issues have been expressed through her music and Alicia Keys also expressed the same. No one knew what to expect from an Alicia Keys-hosted Grammys, but now we know.
