Ashton Kutcher and Mila Kunis have revealed the name of their baby girl!

Taking to his website last night (Oct. 2), the 'Two and a Half Men' star penned a post entitled, 'One of these is Mila and Ashton's baby… and her name is Wyatt.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world," he wrote. "May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy."

But because he still has a little bit of that 'Punk'd' host left in him, Kutcher couldn't resist playing a little joke on the media, posting several pictures of different newborn babies (and two animals!), asking fans to take a stab at which pic was baby Wyatt.

"Can you guess which one is ours, or does it really matter?" he joked. "All babies are cute." Too true. (Want to guess which baby is Wyatt? Check out the post -- and see the pictures! -- here.)

Little Wyatt entered the world on Sept. 30. She is the first child for Jackie and Kelso Mila Kunis and Ashton Kutcher. Congratulations to the happy family!
