Ciara is flaunting her baby bump ahead of her approaching due date

The pregnant 31-year-old singer, who is expecting with husband and NFL star Russell Wilson, showed off her belly in a photo Sunday on Instagram.

"Sunday Vibes.." she captioned a black and white picture of herself smiling at the beach.

Ciara and Wilson, a 28-year-old quarterback for the Seattle Seahawks, married in July after more than a year of dating. The couple announced in October that they are expecting their first child, and have been vocal about their excitement since.
