The singer, 34, announced on Instagram Thursday that she is pregnant.
“Number 3,” she wrote, alongside a photo of her showing her baby bump in the Turks and Caicos Islands.
Wilson also revealed the news on his Instagram page.
“Number 3,” the Super Bowl champion captioned a picture of him in the foreground while his wife is blurred behind him. Wilson also just so happens to wear a No. 3 jersey for the Seahawks.
The couple, who have been married for three years, are parents to daughter Sienna Princess Wilson, born in April 2017.
Ciara also has a 5-year-old son from a previous relationship with rapper Future.
After she and Wilson had their daughter, she welcomed her new bundle of joy with a special message on Instagram.
"No matter how big the wave, we will always be your calm in the storm," she wrote, in part.
