Ashton Kutcher revealed his newborn daughter's name on his personal website on Thursday.

Mila Kunis Shows Off Baby Bump On The Red Carpet 

"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."

Kutcher also included some humor into his post. The 36-year-old shared a series of random babies and wrote, "Can you guess which one is ours, or does it really matter? All babies are cute." Of course, it's impossible to tell which baby from the list is the one Mila Kunis gave birth on Tuesday night in Los Angeles. I'm sure some fans will have fun guessing.

On Facebook, Kutcher also joked, "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."

Mila Kunis Sends Angry & Comical Message To Future Dads 

During an appearance on The Ellen DeGeneres Show in May, Kunis, 31, revealed that she planned to have a natural labor without an epidural. "I'm going to do it as all natural as I possibly can unless there's an emergency or something that should wrong," Kunis said.

Kunis and Kutcher, who got engaged in February, met when she was only a teenager on the set of That '70s Show. Kunis revealed why she finds their long history "comforting." 

"Not only did it introduce me to my fiancé," she told W Magazine about the show in the August issue," but I'm so grateful that all my mistakes are recorded for posterity. I went through puberty on television! I grew five inches while I was on that show, and I had so many different eyebrow shapes! I went through everything embarrassing that a girl can go through in front of my fiancé. There's no question that he's seen the worst."
