The new baby joins his older brother, 4-year-old Egypt Daoud, who was looking forward to being a big brother, People reported.

"I think he's super excited because he's not going to be the youngest anymore," Keys said back in October. "He's always kissing my belly."

"Happy anniversary to the love of my life," she wrote 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 later revealed her due date during an interview with "The View," Us Weekly reported.

"They tell me Dec. 31," she said.

"Being a mother has definitely given me more of a fierceness and an understanding of just what I believe in, that much more," Keys added about motherhood.

Swizz Beatz has three other children from previous relationships: Nicole, Prince Nasir and Kasseem. He is now the proud father of five children; one girl and four boys.
