Us Weekly revealed in May that Panettiere was pregnant with fiancé Wladimir Klitschko. "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 told Glamour. "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."

The couple got engaged last year after a brief split. "They're in similar circles, where they understand the schedule, the work ethic, the social aspect," Panettiere said about dating athletes, as opposed to actors, "but they're not exactly in your industry, so it works out well."
