Singer Alicia Keys welcomed her second son with husband Swizz Beatz early Saturday.

The baby has been named Genesis Ali Dean and his mother took to photo-sharing site Instagram to share her feelings and posted "The joy of joy is joy!! It's a boy!! We are so greatful!! #blessings!!" The couple is already parents to their four-year-old son, Egypt, who was "so ready" to be a big brother long ago, reports eonline.com.

"He's not going to be the baby anymore. He's already preparing. He has like a little doll where he's like, 'Am I supposed to be doing this? Am I supposed to be doing that?' He's so ready. It's a blessing," Keys said previously.

While this is the second child for the singer, her husband has three kids from past relationships.
