Smirnoff, who preferred not to disclose the baby’s father’s identity at the time, has expressed her desire to have a family in recent years.

“I’m at the place in my life that I want to be a mom more than anything and I want to be a wife,” she previously told PEOPLE in 2015, shortly after calling off her engagement to Jason Adelman. “I want to live for another human being and give that little guy or girl everything I have.”
