"Oof, I didn't have it in me, but I could get it out," she said about being a little out breath while singing. "Happy birthday, sunshine. He's doing OK, he's quiet.

"I can hear him, the little sounds. I haven't been able to really see his face yet, I can't wait."

Win is Ciara's second child with Wilson, the star quarterback of the Seattle Seahawks. The couple, who have been married for four years, are also parents to 3-year-old daughter Sienna Princess Wilson.

Ciara also has a 6-year-old son, Future Zahir Wilburn, from a previous relationship with rapper Future.

The couple revealed they had a second child on the way in January and then shared in April that they were having a baby boy with a gender reveal video.
