Ciara Legally Adds Wilson to Son With Future’s Last Name

Ciara‘s son with rapper Future is legally a Wilson … ’cause TMZ has learned the singer added Russell Wilson‘s last to her eldest son’s legal name.

ICYMI … Ciara and Russ hit the US Open this week with their kids — but when Russ posted a shot of Ciara and their family from the stands with the caption, “Mrs. @ciara Wilson Future Wilson & Sienna Wilson,” fans zeroed in on the fact Future Zahir‘s last name was written as “Wilson.” That sparked speculation Russell had adopted him.

Sources with direct knowledge tell TMZ … Ciara has full custody of her 11-year-old, and “Wilson” was legally added to his name a few years back. We’re told Russell didn’t adopt Ciara’s eldest, but the name change is legit.

Ciara and Russ — married 9 years, parents to 3 other kids — looked all smiles courtside. As for Future … he’s stayed quiet, though the last time Ciara was asked about their co-parenting situation, she couldn’t help but laugh.
