Ashton Kutcher and Mila Kunis just became the proud parents of a baby girl.
Now get ready to play "Maybe Baby."
According to Kutcher's playful website posting, one of six adorable newborns is their daughter, but he won't say which one.
The Two and a Half Men star's cheeky message read, "Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. Can you guess which one is ours, or does it really matter? All babies are cute."
INSIDE EDITION went to obstetrician Dr. Lisa Masterson of TV's The Doctors to try to solve the mystery along with a baby photo of Kutcher we were able to dig up.
Dr. Masterson chose one photo and said, "This is actually my bid in the baby game. This baby to me, has the appearance of a newborn more than the rest of them."
Some believe this cutie is definitely the one.
Because she's wearing the distinctive cap and blanket all newborns are given at Cedars-Sinai Medical Center in Los Angeles, where the Kutcher baby was born.
Other than the joke, there's a deeper reason why Kutcher is making it a guessing game.
He hates paparazzi and takes a poke at them with a Facebook message that said, "Here's your baby photo. Well, one of them is. Now can the helicopter please stop hovering over our house, there is a baby sleeping inside! And she's super cute."
We wish Kutcher and Kunis good luck with their baby, whichever one she is.
