Keys announced the big news of their latest addition across social media Sunday (December 28).

Last September, Keys said both a new album and her next child could arrive this winter.

Keys, who often releases albums in November and December, says she is preparing for another delivery at the end of the year: her second baby. “December album? Well, I know one thing. I’m having a December baby,” the singer said with a laugh in an interview Tuesday, Sept. 3, 2014 (AP)

Alicia and Swizz welcomed their first child together four years ago.

This is the second child for the couple, who have a 4-year-old son, Egypt Daoud. Swizz has a daughter, Nicole, and two sons, Prince Nasir and Kasseem, from previous relationships. (Rap-Up)
