The exciting baby news was confirmed to ET by Kunis' rep earlier this month. Kunis and Kutcher, 38, are already parents to 1-year-old daughter Wyatt Isabelle.
Last month, ET caught up with Kunis, where she adorably revealed how life has changed since becoming a mother. "I reprioritized my life, in all honesty," she gushed. "I traveled through all my 20s and I was very selfish... In a good way, not in a way I regret. And I think having a kid made me realize how incredibly selfless I want to be."
"It does change the way you think and look at life," she added. "I would never trade it for the world… But I know that when [Ashton and I] decided to have a kid, we were ready to no longer be selfish. Or at least start the process, because innately, as humans, we are really selfish people."
The happy couple, who tied the knot in a small, intimate ceremony at the Parrish Pioneer Ranch in Oak Glen, California, will be celebrating their first anniversary on July 4. To hear more on their nuptials, watch the video below.
