The 33-year-old singer and her husband, Swizz Beatz, welcomed their second child together, a baby boy.

"The joy of joy is joy!! It's a boy!!🌟🌟🌟🌟 we are so grateful!! #blessings!!" she wrote on Instagram, along with a photo of her newborn son's footprints.

Genesis Ali Dean was born at at 1:52 a.m on Dec. 27, weighing in at 6 lbs., 5 oz. He's also the younger brother to Alicia and Swizz's first son, Egypt, 3.

"Being a mother has definitely given me more of a fierceness and an understanding of just what I believe in, that much more," she told 'The View' in September.

Congrats to the growing family!
