When it comes to what really matters, you bet.
Despite the couple's legit superstar status in both the magazine cover and box office departments, Reynolds having his biggest hit to date with Deadpool in February and Lively owning both The Shallows and her first Woody Allen film this year, they've held fast to a very particular rule since the birth of their first child, James, who arrived...sometime toward the end of 2014.
Well, we know now that James' birthday is Dec. 16, thanks to the well wishes from Dad on her first birthday last year (oh, we wrote that down!).
But Reynolds and Lively—who have now welcomed their second child together, all specifics TBD—never formally announced that their daughter had arrived, and her existence wasn't reported on until almost three weeks after she was born, happily, healthily and stealthily.
