The "A Woman's Worth" singer attended the annual awards show with her husband Swizz Beatz.
Last month, Keys got honest about overcoming her physical insecurities growing up -- particularly, her complex relationship with makeup -- in a candid essay for Lena Dunham's Lenny Letter. Not surprisingly, her self-scrutiny only got more intense once she got famous.
"This was the harsh, judgmental world of entertainment and my biggest test yet," she explained. "I started, more than ever, to become a chameleon. Never fully being who I was, but constantly changing so all the 'theys' would accept me.”
"Every time I left the house, I would be worried if I didn't put on makeup: What if someone wanted a picture??" she admitted. "What if they POSTED it??? These were the insecure, superficial, but honest thoughts I was thinking. And all of it, one way or another, was based too much on what other people thought of me."
Keys later credited her now healthier level of self-esteem to discovering meditation, and an enlightening moment when she allowed a photographer at a photo shoot to take pictures of her without any makeup on.
"I hope to God it’s a revolution," Keys wrote. "'Cause I don’t want to cover up anymore. Not my face, not my mind, not my soul, not my thoughts, not my dreams, not my struggles, not my emotional growth. Nothing."
"We were together today and it's like a total love fest," Cyrus told host Jimmy Fallon about working with Keys. "Her and I are both extremely mellow. I think people, when they put girls on TV, they [think], 'This is how we're going to get the ratings up because there's going to be drama and there's going to be cat fights.' They're thinking that we're just going to bring kind of the dramatics to the show and we couldn't be more opposite."
