Wladimir Klitschko & Hayden Panettiere: Meet Their Family

Wladimir Klitschko may be one of the most menacing human beings you'll ever see, standing at 6-foot-6 and boasting one of the most dominant resumes (64-4, 53 knockouts, various world titles) in the history of boxing. But he's also a gentle family man.

That starts with his partner, actress Hayden Panettiere, who measures in at about 18 inches shorter than Klitschko. "I know that I'm small, but he's large," says the Nashville star. "That's how we met. I said, 'You're huge.' And he said, 'You're tiny.' And that was it."

Engaged in 2013, Klitschko and Panettiere have yet to officially tie the knot, but they did welcome a daughter, Kaya Evdokia Klitschko, to the world on December 9, 2014. “She can communicate with her eyes and smile,” said the former heavyweight champ. “Even if you’re tired and haven’t slept enough, when you look at your child’s eyes, [it’s like], ‘For you, little angel, I’m going to do everything. Literally everything.’ I don’t know what appreciation she’s expressing but it’s something like, 'Thank you for being here in my life, Dad, and being around.’ It’s something that gives you a boost of energy."

In addition to his fiancee and daughter, Klitschko's support system also includes his mother (his father passed away in July of 2011) and successful older siblings. Most are well aware of his brother, Vitali, who was also a dominant world champ, while his sister-in-law Natalia (Vitali's wife) recently released her own album.

Klitschko's ability to sustain success for so long hinges on the strong support of his family, and you can click through the gallery to see and learn more about his fiancee, daughter and everyone around him. (Getty)
