Russell Wilson and Ciara are making another business move together -- by publishing their first children's picture book!
The couple announced the news Wednesday ... saying they've teamed up with Penguin Random House to release the book titled "Why Not You?"
"I am so excited to share that Ciara and I will be publishing our first book for kids next spring," the Seattle Seahawks QB said on IG.
The picture book intends to "encourage readers to see themselves achieving their dreams, no matter how outrageous they may seem," according to PRH.
