But it's not only the couple who were excited with the birth of their baby son. Their eldest son, 4-year-old Egypt Daoud, was also looking forward to his baby brother's birth.

"I think he's super excited because he's not going to be the youngest anymore," Keys was ecstatic when he told People in October, saying Egypt was even kissing her belly.

Keys and Beatz - who already had a daughter, Nicole, and sons, Prince Nasir and Kasseem, from past relationships - announced that they were expecting a baby last July.

"Happy anniversary to the love of my life," Keys posted on Instagram.

"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!" she continued. 

Throughout her pregnancy Keys did not hesitate to show to the world her baby bump.

She was proud, pregnant mom whether walking on the red carpet or singing onstage.

The "No One" crooner even spent time to pose nude for the #WeAreHere Movement.

"It's you and me on a mission to create a kinder and more peaceful world," Keys wrote on Instagram as she unveiled her bump in a sexy nude pic.
