The singer released the track, which features a tribute to her man, and an accompanying video on Tuesday, February 12.
In the song, she praises the football star for accepting her and her son from her romance with rapper Future, singing: "I should've known when you took my son as your own/I’m not saying I ain't like all the carats and the stone/It's just your love that I want/Now it's me and you against the entire world, the entire world/I see our love when I look at our baby girl, I'm a lucky girl."
The couple welcomed daughter Sienna Princess in 2017.
The song tribute comes just days after the "Like A Boy" hitmaker praised Wilson during a sit down at the 2019 MAKERS Conference.
"I'm a strong woman but I need a strong man by my side, and I know I can do anything that I put my mind to," she shared. "But I think at some point in time it's good to let somebody also do some stuff for you too. The best thing is when you have a man that's strong. A strong man that's smart and wise and also loves you and has your back and lifts you up and empowers you."
Ciara and Russel tied the knot in 2016.
