Ciara and Russell Wilson are expecting their first child.Reuters

Cira's 31st birthday was special for many reasons. The singer received a lot of love not just from her family and friends but also from millions of fans, who couldn't be happier that she is pregnant and expecting her first baby with Seattle Seahawks quarterback, Russell Wilson.

On Tuesday night, Ciara and husband Wilson posted cute messages on their Instagram accounts, confirming that their family is growing bigger. 

Ciara uploaded a photo of Wilson caressing her tiny baby bump and captioned it: "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's Instagram post confirms rumours that have been circulating for a while. Fans of the singer had earlier wondered if she was pregnant when she appeared in a video with former Miss America pageant winners. 

These rumours continued when she wore an over-sized white suit at Revlon's event in New York City earlier this month.

Ciara's recent choice of clothing was in stark difference to the fitted, figure-hugging dresses that define her style. And many who draw inspiration from Ciara's style were baffled when she continued to wear loose clothes that concealed her baby bump.

It's not yet clear just how many months pregnant Ciara is, but she has often said that motherhood is one of the best jobs in the world. 

While talking about being a mother to her two-year-old son, Future Zahir, she told Hong Kong's Lifestyle Magazine, Legend, "You also understand love much better. It's the greatest force, the greatest thing. Before this, I don't think I understood love honestly, but now I'm better at love, better at loving, better at patience."

Ciara and Wilson tied the knot in July 2016, after being engaged for four months. The couple earlier spoke about expanding their family and are now no doubt living that dream.
