Congratulations to the newest celebrity parents on the block!

Ashton Kutcher and Mila Kunis welcomed a baby girl into the world on Tuesday, according to People Magazine.

“She’s here and healthy,” a source told People. The magazine went on to report that the baby’s name has been a known secret for sometime. Only Kutcher’s mother knew it ahead of the birth, but those close to the couple did admit that Kunis and Kutcher liked unisex names.

Adding a bit of mystery into the news, the Hollywood power couple decided to hold off on releasing the baby’s name to the public until Thursday, when Kutcher made the announcement on his website.

CNN reports that the couple went with the name Wyatt Isabelle Kutcher.

“Mila and I would like to welcome Wyatt Isabelle Kutcher to the world,” he posted on his website.  “May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy.

As always, Kutcher posted the announcement with a comedic twist. Along with a photo of their newborn, the proud father posted it alongside eight other photos and asked his fans to guess which one was his new daughter.

“Can  you guess which one is ours, or does it really matter?” he wrote. “All babies are cute.”

This is the first child for Kunis, 31, and Kutcher, 36. They started dating in 2012, shortly after Kutcher separated from his then wife, Demi Moore.

The new parents got engaged earlier this year. Kutcher and Kunis first met when they worked side-by-side on the Fox  sitcom That ’70s Show.
