Though the couple has kept any wedding plans under wraps since Wilson popped the question during a romantic trip to the Seychelles in March, Ciara gushed about her future husband in a recent cover story for Essence.
“I remember telling my friend the kind of guy I wanted: a God-fearing man with a very fun spirit who loves kids and would really, truly care for me,” she said. “Marriage is something I look forward to. I believe in family, and the beauty of two people committing to spend their lives together.”
