Hayden Panettiere is pregnant.

The Nashville actress and her fiance, boxer Wladimir Klitschko, are reportedly expecting their first child together, it has been claimed.

"Hayden is totally pregnant!" a source said.

The 24-year-old actress - who got engaged to the 36-year-old athlete last year after a three-year on/off romance - previously admitted she was keen to start a family and felt like she was "born" to be a mother: "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. 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."

And the former Heroes star has even speculated on what her future children would look like. "He's got bowlegs and I've got knocked knees, so they're going to have straight legs. And they'll be normal height," she previously joked.
