The former Heroes actress also said she and the Ukrainian heavyweight professional boxer were working with an interior decorator to fix the baby girl's room.

The star also opened up about her future with her beau in the May 2013 issue of Glamour magazine and revealed how much she wanted to be a mom.

"I don't really have a plan. I've lived a very big life, and I don't feel my age, and I feel like I was born to be a mother," she said. "Sometimes people speak about [having kids] like, 'Your life ends-you're never going to be able to do anything again!' And I'm like, 'What are you talking about?' Motherhood is the most beautiful, exciting thing, and there's nothing that I feel like I can't accomplish while having children in my life."

 It's a girl!
