Ashton Kutcher on Thursday revealed on his website that he and Mila Kunis named their newborn daughter Wyatt Isabelle Kutcher.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world," Kutcher wrote of his first child, who was born on Tuesday. "May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy."

The baby picture is a bit of a guessing game.

Kutcher uploaded eight pictures on his website (which also included one picture of a goat and one of a dog), adding, "Can you guess which one is ours, or does it really matter? All babies are cute."

The star also posted on his Facebook, "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."

Even though all babies are cute, the mystery still remains and fans are anxious to know which one is theirs.
