Wilson followed up with an Instagram snap of his own, featuring his gorgeous wife standing in the sun. "Forever, the Best Present," the Seattle Seahawks quarterback wrote.

Four months after tying the knot in a beautiful castle in Cheshire, England, the couple announced that they are expecting their first child together. Their newest bundle of joy will be the first for the NFL star, while Ciara shares 2-year-old son Future Zahir with her ex, rapper Future.
