The Grammy winning musician, who is already mom to 3-year-old Egypt, shared the adorable picture of herself, 33, and her husband, 35, cradling her blossoming belly, as they celebrated their fourth wedding anniversary.
"Happy Anniversary to the love of my life @therealswizzz!!" the "Empire State of Mind" singer wrote. "And to make it even sweeter we've been blessed with another angel on the way!! You make me happier than I have ever known! Here's to many many more years of the best parts of life!"
Last year Keys admitted her and Beatz's path to love was not straight forward.
"Honestly, I didn't really like him that much," the singer told Marie Claire UK. "I thought he was too ostentatious."
But after refusing to work together many times, Keys eventually gave in, and discovered she’d been too quick to judge the handsome music producer.
"I think we've taught each other a lot," she says of her husband who she married on the French island of Corsica in 2010. "He's taught me to live more fully, and I think I've taught him to live more deeply."
