Kunis was spotted out in Beverly Hills, California, and the expectant mom looked wonderfully retro in the long-sleeved, short-hemmed, button-down number.
The bright, busy outfit looked just like something her That 70's Show character, Jackie Burkhart, might have rocked, and Kunis couldn't have looked cooler, pairing the patterned top with simple, white sneakers.
Kunis and her husband, Ashton Kutcher, first met while co-starring on the Fox sitcom over a decade ago. The pair struck up a romance in 2012, six years after the show went off the air, and got engaged in February 2014.
Kunis and Kutcher welcomed their first child, daughter Wyatt Isabelle, in October 2014, and later tied the knot in a private ceremony in Oak Glen, California in July 2015. The cute couple announced that they were expecting their second child in June.
Last month, the Bad Moms star spoke with ET about her upcoming bundle of joy, and how the second pregnancy is wildly different than the first.
"I think with the first one, you're so enamored with the initial experience that I was constantly checking the app, 'What fruit size is the baby? Is it the size of a grape or an avocado?'" Kunis shared. "Now I'm like, 'Wait, how far along am I?' You're busy running after the other one and working full time." Check out the video below to hear more.
