The 'Two and a Half Men' actor, Ashton Kutcher, recently took to social media to reveal the name of his newborn baby girl with fiancée Mila Kunis.

The celebrity couple's baby, who was born on Sept. 30, is named Wyatt Isabelle Kutcher. The actor announced the name in a Facebook post, along with a link to his website which currently features several baby photos as well as pictures of baby animals.

"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 on his Facebook page.

Fans, however, will have to guess which of the baby photos is Wyatt's.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world," the 36-year-old actor wrote on his website, "May your life be filled with wonder, love, laughter, health, happiness, curiosity and privacy. Can you guess which one is ours, or does it really matter? All babies are cute."

Mila, 31, gave birth at Cedars Sinai Hospital in Los Angeles. It's the first child for both actors, who confirmed their engagement earlier in the year.

Throughout her pregnancy, the first-time mom showed off her growing baby bump, attended weddings and enjoyed music festivals with Kutcher, and even indulged on frozen yogurt and burgers as well as spending time with their family members.

Last May, the 'Forgetting Sarah Marshall' actress told host Ellen DeGeneres that her cravings included pickles and sauerkraut.

"[Ashton] assumed that I was [going to] have goofy cravings, so he stocked our secondary fridge with weird food - just, like, pickles and sauerkraut, or, like anchovies and ice creams - just in case at one point during this pregnancy, I'd be like, 'I really want something," Kunis said during a guesting at 'The Ellen DeGeneres Show'.

Kutcher's brother, Michael, told US Weekly that the first-time parents are like Ross and Rachel from the popular sitcom 'Friends'.

"It'd be like Ross and Rachel getting married," Michael Kutcher said, "They make such a great couple."
