Ciara and Russell Wilson are expecting their first child together, the "I Bet" singer confirmed on her 31st birthday. The news comes just a week after pregnancy rumors first began swirling.

"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," Ciara wrote on her Instagram account.

The Seahawk quarterback also took to his Instagram account to share the good news with the same picture on Ciara's Instagram.

Ciara has a 2-year-old son Future Zahir with her ex, rapper Future, with whom she was previously engaged from October 2013 to August 2014.

The singer fueled pregnancy rumors after she wore loose-fitting clothing to the Revlon x Ciara launch event Oct. 18. She tried to conceal her growing baby bump with an all-white, loose-fitting blazer and matching pants.

Ciara and Russel got married in July in a lavish ceremony at the Peckforton Castle in Cheshire, England.
