Both stars took to Instagram on Tuesday to share the good news with a heartwarming black and white snapshot of the singer laying in repose with her NFL star husband, as he wraps his arms around her and rests his hands on her stomach.
"The Greatest Blessing of All. Forever Grateful. #BabyWilsonOnTheWay," Wilson, 27, captioned the cute shot.
Ciara, who turned 31 on Tuesday, shared the same pic, which she captioned, "On this special Birthday I received an abundance of love from friends and family.. and I'm excited to Finally share one of the Greatest Gifts of All that God could give."
Their upcoming bundle of joy will be Wilson's first child, while Ciara shares 2-year-old son Future Zahir with her ex, rapper Future.
The couple, who started dating in early 2015, got engaged in March 2016 and tied the knot four months later in a lavish ceremony at Peckforton Castle in Cheshire, England.
ET caught up with Wilson shortly after the couple exchanged their vows, and the Seattle Seahawks quarterback opened up about the possibility of having more kids with his new bride. Check out the video below to hear what he had to say.
