In October, the "Jupiter Ascending" star told Business Insider she was definitely interested in expanding the family. When asked about whether she was open to the idea of having more kids in the future, she said, "Not today, but yeah, absolutely. For sure!"

The soon-to-be mother-of-two opened up about raising a family last month. Kunis shared that once she and Kutcher decided to have a child, they had made up their mind that they will no longer be selfish.

She added that it is human nature to be selfish and in order to raise a child, one must strike a perfect balance between being "a great partner, a great wife, a great woman and be yourself," while still being responsible for a baby.  It's definitely a learning process," she added.

Ashton also gushed about his wife, describing her as "the greatest mom." The actor said that he goes to work every day and when he returns home to her it feels like everything went well.

"The Ranch" actor added that even though everything didn't go as well, his "incredible" wife would never let him know.
