Obama tweeted that she dropped in at the Grammys to support Keys.
Next, when it was Obama's turn to talk, the audience gave a rowdy round of applause as she began. She and her husband, former US President Barack Obama, signed deals for a book apiece with Penguin Random House a month after Obama left office in January 2017. "Music helps us share ourselves, our dignity and sorrows, our hopes, our joys. Music has always been the one place we can all feel truly free". Diana Ross also took the stage and led a sing-along to some of her most memorable songs to celebrate her 75th birthday.
At the start of the segment, Lady Gaga - a triple victor so far on the night - said: "They told me I was weird". Obama asked, looking around at the women on stage with her. "Thank you so much for this gift I am completely shocked".
Flanked by two pianos ― one black, one white ― Keys delved into a cabaret-style medley of songs she wished she'd written, including Roberta Flack's "Killing Me Softly", Nat King Cole's "Unforgettable" and Lauren Hill's "Doo-Wop (That Thing)". "Music shows us that all of it matters".
The music business will be partying ahead of the show at celebrations including the pre-Grammy gala hosted by the Recording Academy and Clive Davis, the Family Tree Entertainment music managers pre-Grammy brunch and the Music Is Universal artist showcase hosted by Lucian Grainge.
After her second, for the song named after the superstar's aunt, Lady Gaga called the award "more than me & my family could ever dream of". While he was nominated for song of the year for his single "In my Blood", that Grammy went to Childish Gambino for "This is America". Last year, only one solo female artist received an award in any major category: Alessia Cara for Best New Artist.
