While the actress has yet to address the reports she did tell Glamour in a 2013 interview that she "was born to be a mother."
"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," she said at the time.
Panettiere revealed she was engaged to Klitschko while visiting Live With Kelly and Michael in October 2013. The couple met at a book party in 2009 and dated until May 2011. They got back together in the spring of 2013.
