Ciara made it official on Sunday. She and Russell Wilson are expecting their fourth child, and going by the numbers she flashed in her own Instagram post, this one's arriving as "Baby Cinco."

The announcement itself was low-key by celebrity standards but landed exactly the way it was meant to. Ciara posted a carousel showing herself hanging white t-shirts on a clothesline, an ordinary domestic image, before slipping in the reveal: a tiny baby onesie at the end of the line. She's visibly pregnant in the photos, throwing up five fingers in a couple of frames. Wilson stands beside her doing the same. According to The Shade Room, one clip in the set even caught the couple's daughter Amora Princess Wilson pretending to photograph her mother, unaware she's about to become a big sister again.

Ciara's caption did the rest of the work. "One more person to Love," she wrote, with a raised-hand emoji and a black heart. No due date, no gender reveal, nothing beyond that. Sometimes that's the whole point.

For longtime followers of this family, the number five is the story here. Wilson has apparently spent close to a year publicly campaigning for what he called "Cinco," and The Shade Room's report frames this pregnancy as him finally getting his wish. Whether that's exactly how it played out at home is between the two of them, but the framing has clearly stuck, because it's all over Ciara's comment section too.

"CiCi said YES to Cinco," one fan wrote. Another put it more bluntly: "I'm crying cause Russ was so dead serious about Cinco. Congrats!" A third, apparently tracking the running joke as closely as the couple's fans do, called Amora "stealing the show" in that photobombing clip.

This will be Ciara and Wilson's third child together. She's also mother to Future Zahir Wilburn from her relationship with rapper Future, and Wilson has been raising him as a stepfather. Add the new baby to that mix and the couple's household goes from four kids to five, matching the number that's apparently been the goal all along.

Ciara and Wilson married in 2016 and have built a public family life around football season, music releases and now, it seems, a running joke about family size that's finally paying off. There's no word yet on when the baby is due, and neither has said anything beyond the post itself. For now, the internet's doing what it always does with this couple: counting fingers, reading captions twice, and waiting for the next update.
