This has been quite a news week for Ryan Reynolds! The actor lent Taylor Swift—who has recently become very close with his wife, Blake Livelyhis actual Deadpool costume for her to wear on Halloween. And on Wednesday night, Reynolds appeared on Conan, even though, as People notes, he “had no film projects to promote.”

So . . . why was he there, then!? Well, Reynolds spent the bulk of his appearance running through potential reasons for his guesting on the show, including the release of a line of prosciutto underwear, and a sex tape with the cast of Fox and Friends. The centerpiece of the bit was his sharing a previously taped clip from The Notebook 2, in which Reynolds and O’Brien kiss quite passionately in the rain. (There is a very post-12:30 A.M.-Saturday Night Live-sketch vibe to the proceedings.) After the clip aired, Reynolds joked around for a bit (“You have the longest tongue in show business,” he told O’Brien) and said that he was “never going home again,” as he would have to answer to Lively.

Lively, with perfect timing, took to Instagram and shared a shot of a Levain bakery cookie (accompanied by a glass of milk), writing that she knew Reynolds had “got himself into huge trouble” on Conan because he had procured her “true love” (yes, referring to the cookie) for her. These two! What wacky hijinks will they get up to (and then Instagram) next?!

Somehow we have gotten this far before reaching what actually seemed to be the reason for Reynolds’s appearance: according to People, he confirmed to O’Brien that he and Lively’s second child is a girl, a younger sister to their two-year-old daughter, James. “Yeah, a lot of estrogen,” he said. “It’s like an American Girl doll took a s--- on my life.” (We presume that quote is not painted on the wall of the nursery.) This confirms what was seemingly implied by his tweet last month which reference a “daughter’s crib.”

There is still, of course, some mystery, as the name of the child remains unknown. How will Lively and Reynolds reveal that?! Will they let Swift announce it in a series of Instagrams (one carefully-art-designed Instagram per letter)? Will Lively host Saturday Night Live, even though she doesn’t have a film coming out right now or anything, just to slip it during the monologue? Or will Lively use the opportunity to launch her new Preserve 2.0 lifestyle brand named after the new child? Even just contemplating the possibility of that is nearly overwhelming.
