Ciara’s son with rapper Future now officially carries Russell Wilson’s last name — and fans can’t stop talking.

Speculation sparked after Russell posted a family flick courtside at the U.S. Open this week, captioning it: “Mrs. @ciara Wilson Future Wilson & Sienna Wilson.” Followers quickly clocked that Future Zahir’s name was listed as “Wilson” — leading many to believe Russell had adopted him.

According to insiders, Ciara has had full custody of her 11-year-old for years, and “Wilson” was legally added to his name a while back. His full legal name still includes his biological father’s last name, Wilburn, but “Wilson” is officially recognized too.

Ciara and Russ — married for 9 years and raising three kids together — looked unbothered and glowing courtside. Meanwhile, Future has kept quiet. The last time Ciara was asked about their co-parenting dynamic, she simply laughed.

With this move, it’s clear: Russell Wilson isn’t just a stepdad — he’s fully cemented in the family legacy.
