Hayden Panettiere's fiancé Wladimir Klitschko thinks she's going to be "an amazing mother."

The heavyweight professional boxer, 38, is thrilled the 'Nashville' actress, 24, is expecting their first child and is looking forward to their lives changing forever.

The Ukrainian athlete told E! News: "When you're going to become a father or a parent, your life is going to change. So I look forward to having my life change for the good and I heard, just recently, somebody said, 'You don't know what love is until you have your first baby, then you know what love is.' So I think I know what love is, but I look forward to getting more knowledgeable about that."

Asked about his fiancée, Wladimir said: "She's an amazing person and I'm more than sure that she's going to be an amazing mom."

The blonde beauty, who previously claimed she was born to be a mother, was very vocal about her desire to start a family to Wladimir.

He said: "Her wish to become a mother and have a child [was something] she's been mentioning and telling me about a lot. You know, every dream will eventually come true and she's going to be more than an amazing mother."

He also hinted they are planning to keep the sex of their baby a surprise until the birth, saying: "It's not important where the baby is going to be born, it's not important [whether it's a] boy or girl, what's important is that the baby's healthy."
