She later posted the photo below on her Instagram page with the caption, "It's a girl!"

Panettiere said that she’s working with an interior decorator to fix the baby girl’s room, but she’s not going for the usual pink theme. The 25-year-old and the Ukrainian heavyweight professional boxer are also still deciding on baby names.

"We have to make sure that it is American and Ukrainian all at the same time," she said. "That's a little rough...we're still working on it."

Panettiere opened up about her future with her beau in the May 2013 issue of Glamour magazine and revealed how much she wants 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."
