NanoReads doesn't host 5 Adults vs 1 Secret Baby, and neither does any reading app, because it isn't a book. It's a guessing game from The Kevin Langue Show on YouTube: five adults pretend to be a child, one real child hides among them, and the panel has to work out which is which.
I checked before writing that sentence. Our catalog has no title containing "5 adults", "adults vs" or "secret baby" other than one werewolf serial that turns up below, and a search of the production database gives the same answer. So if you got here from a romance app's search bar, or from a TikTok that made it sound like a serial, this page is going to be more useful than the one you expected, just not in the way you expected. Here is who types this query, and what each of them is after.
Three people search this title, and they want three different things
-
The one who saw the clip and wants the full video
You want YouTube. The episodes are on Kevin Langue's channel under the titles 5 Adults vs 1 Secret Baby and 5 Adults vs 1 Secret Baby (Boy Edition); the Boy Edition is also listed on IMDb as a 2025 episode of The Kevin Langue Show. A version with the Beta Squad was posted on the NDL channel. The show is also listed as a podcast. That's everything I can verify, and I'm not going to invent view counts.

The one who misremembered a serial's title
This is the biggest group, I think, and it's an understandable mistake: number, "vs", "secret baby" is exactly the cadence of a webnovel or short-drama title. The books you're probably half-remembering are Secret Baby Billionaire Daddy, Divorced With a Secret Baby or Ms. CEO's Secret Baby Daddy. We've written a page for each that says where it lives, because we don't host those either.

The one who wants the trope and doesn't care about the title
Secret baby, in romance, means a heroine who hides a pregnancy or a child from the father, usually a rich or powerful man, until the story forces the reveal. It's a staple of the billionaire romance shelf and of werewolf serials, where the child is often an heir. If that's what you came for, skip to the six books below. One of them is the real thing; the other five are the nearest the catalog gets, and I've said exactly how near.
Why a comedy segment reads like a romance title
Two things collided. The short-drama apps have trained everyone to read "Secret Baby" as a genre marker, the way "Alpha" or "CEO" is; the billionaire romance list on this site has a whole run of titles built the same way. And Langue's segment titles are written like thumbnails, with a number up front and a "vs" in the middle, which is also how serial platforms name their books. Put those two habits together and a search engine can't tell the difference, so it shows a romance reader a comedy panel and a comedy fan a shelf of alpha heirs. Neither is wrong to be confused.
The trope and the game do share a joke: in both, somebody in the room knows something about a child that everyone else is trying to guess. That's where the resemblance ends.
👶Six serials on NanoReads, sorted by how close they get
Every note is from the book's own description and tags; where a blurb is vague, so am I. Heat runs high on this shelf: four of the six carry steamy or erotic tags, and two carry an abusive tag, which I've marked. The first chapter of each is free to read.

Free- My Enemy Alpha's Secret BabyThe real thing
For five years Lena has hidden Leo, the son of Warlord Alpha Kane, the tyrant who fathered him without knowing. Then the wasteland runs out and she's dragged in front of him. This is the only serial in the catalog with the secret-baby tag, and the blurb hits the trope's two beats in its first three sentences: the hidden child and the moment the father finds out. Tags include abusive, ruthless, steamy and erotic, so expect a dark, explicit werewolf book. Our werewolf romance hub has the wider shelf. Read the first chapter free. - His Painted LiesPregnancy, but not hers
Celebrated artist Seraphina Bellweather walks in on her husband with his pregnant new muse on her own opening night; he calls the muse his "masterpiece in the making" and her work stale. The pregnancy tag is real, but it belongs to the other woman: this is a betrayal-and-comeback billionaire story with no hidden child in it. Abusive, erotic and steamy tags. Read the first chapter free. - The Doctor's OrdersSame author, same setup
Dr. Lena Hanson, a cardiothoracic surgeon, finds her husband with a pregnant nurse. Seraphina Cole is clearly working a template here, and if you liked one you'll like the other; if you wanted a heroine hiding her own child, you'll wait in vain in both. Same heat tags as above, same abusive tag. First chapter free. - Lies & BetrayalPregnant heroine, real author
A pregnant girl stuck in a controlling, abusive relationship with a narcissist who is also dating the supposed cousin they live with, with no job, money or phone. Written by an independent author, filed under young adult, and the heaviest premise on this shelf by some way; the blurb reads like lived experience rather than trope. No heat tags at all. The first chapter is free, and go in knowing it isn't escapism. - Fractures of Falcon HeightsSingle mother, boss
Nina Delgado, a single mother paying off her late husband's debts, takes a job under a ruthless boss named Miles Falcon, and someone from her past resurfaces. Single-parent and billionaire tags, no pregnancy, no secret; this is the "child already exists and complicates the office romance" cousin of the trope. No explicit-heat tags, so likely the mildest of the billionaire four. Open chapter one free. - Nanny in RomeNanny to a single dad
David hires his best friend's now-grown daughter Selina as the nanny for his son on a work trip to Rome, and the suite is small. Boss, nanny, CEO and forbidden tags with the full steamy-erotic set. The child is the reason they're in a room together, which is the loosest possible fit for "secret baby", and I've kept it because it's the closest the catalog has to the glossy short-drama version of this trope. Start it free.
If none of these is the book you half-remember, the books-like finder takes a title or a plot fragment and searches the catalog for the nearest match, and the spice level checker will tell you what "erotic" means on the tag set above before you commit to a chapter.
The four versions of this question
Is 5 Adults vs 1 Secret Baby free?
Yes, in the sense that it is a YouTube video. The episodes titled 5 Adults vs 1 Secret Baby and 5 Adults vs 1 Secret Baby (Boy Edition) are posted on Kevin Langue's YouTube channel, and The Kevin Langue Show is also distributed as a podcast. There is no paid book, serial or app version to unlock, because there is no book.
Where can I read 5 Adults vs 1 Secret Baby online?
You can't, because it isn't a written story. It is a game segment from The Kevin Langue Show in which a lineup of adults imitate children and the panel tries to pick out the one real kid. NanoReads does not host it and neither does any reading app. If you were actually looking for a secret-baby romance with a similar-sounding title, the closest catalog match on NanoReads is My Enemy Alpha's Secret Baby, whose first chapter is free.
Is 5 Adults vs 1 Secret Baby completed?
It isn't a serial, so there is no chapter count and nothing to complete. It is a recurring format: at least two editions exist on Kevin Langue's channel (the original and a Boy Edition, the latter also listed on IMDb as a 2025 episode of The Kevin Langue Show), plus a version featuring Beta Squad posted on the NDL channel. Whether more editions follow is up to the show.
What is 5 Adults vs 1 Secret Baby about?
It is a guessing game. Several adults do their best impression of a child, one actual child is hidden among them, and Kevin Langue and his guests question the lineup to work out which voice is real. It has nothing to do with the romance trope of the same name, where a heroine hides a pregnancy or a child from the father; the title just happens to use the same two words.
