The Hollywood A-listers welcomed daughter Wyatt in October, 2014.
During her appearance on "Entertainment Tonight", she said she is determined to expand their family.
"I'm not pregnant... But absolutely I do want to have more kids one day, for sure," she said.
Kunis is currently promoting her new movie, "Bad Moms", which also stars Kristen Bell, Jada Pinkett Smith and Christina Applegate.
All four women are mothers and Kunis' eagerness to have more babies was partly inspired by spending so much time with her fabulous maternal castmates on set.
