Just two days after welcoming their newborn baby girl into the world, proud first-time parents Mila Kunis and Ashton Kutcher are now revealing their daughter's name and have opted to play a fun guessing game with fans who wish to see they baby's first photo.

E! News reports that Kutcher took to Facebook on Thursday to tease his baby's photo and announce the baby's name which we now know is Wyatt Isabelle.

"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," Kutcher wrote as the caption to his Facebook post that includes the link to his Aplus website which incorporates a series of baby photos -- including photos of baby animals -- to keep fans guessing which photo is actually baby Wyatt.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy," Kutcher writes on his Aplus website. "Can you guess which one is ours, or does it really matter? All babies are cute."

Although neither Kutcher nor Kunis have confirmed which out of the six photos posted on Aplus is actually of Wyatt, TMZ claims to know which photo is actually of Kunis and Kutcher's little bundle of joy.

"...our crack photo team figured it out ..." a TMZ rep writes. "Only one of the babies was wearing the swaddle and cap that are uniquely provided by Cedars-Sinai Medical Center ... where Mila gave birth Tuesday morning."

Prior to giving birth, Kunis revealed on "The Ellen DeGeneres Show" that she planed to give a natural, epidural-free birth.

"The hospital that I'm going to be laboring in does a midwife, you know, doula type of thing," she said. "I'm going to do it as all natural as I possibly can unless there's an emergency or something that should go wrong. I did this to myself, I might as well just do it right. I wanted this!"

Now that baby Wyatt has arrived, an Us Weekly source reveals that Kunis and Kutcher "are so happy" about their "healthy baby girl."
