6 things to know about Wladimir Klitschko's long-term love Hayden Panettiere

She's a former child star

Hayden successfully transitioned from child actress to tv star with early roles in 2000's Remember The Titans, as well a recurring role in American daytime soap One Life To Live when she was just four years old.

She has been in a relationship with Wladimir for eight years

It hasn't been all smooth sailing for the pair - they first met in 2009 and eventually split in 2012, but like all great romances - tacos brought them together again in 2013 and they became engaged just a few months later.

She said she knew he was "the one" after their break-up, "It means a lot when you experience life with someone, then you experience life without him and decide that you don’t want to live without him.

"You date, you try to be with different people, you make mistakes, and you get to know yourself in the process,’ she explained. ‘And in the end you want to be with someone who makes you the best version of yourself," she told Brides magazine.

She is a devoted mother

Hayden and her long-term love have a two-year-old daughter Kaya together and she said motherhood has shifted her priorities in a positive way.

"I can’t say that anything is "the norm" about any day of the week now that I’m the mom. She gets her hands in just about everything, and my biggest job at the moment is keeping her alive!"

She is a mental health advocate

The mother-of-one has been praised for her honesty about her battle with depression, checking into rehab in September 2015 and again in May 2016 for treatment for postpartum depression.

"You feel off. You don’t feel like yourself. But I think I'm all the stronger for it. And I think I'm a better mom because of it. Women are so resilient and that’s the incredible thing about them."

"It doesn’t make you a bad person, doesn’t make you a bad mother. It makes you a very strong, resilient woman. You’ve just got to let it make you stronger."

She's a bonafide tv star

Wladimir might be a superstar in the boxing world, but Hayden's name carries more weight in Hollywood. She's best known for playing indestructible Claire Bennett in 2006's Heroes and most recently starred opposite Connie Britton in the impossibly juicy Nashville, for which she earned two Golden Globe nominations.

She can seriously sing

Fans of Nashville know of her impressive singing ability, but she even has a Grammy nomination to prove it: in 1999, her version of My Hero Is You for A Bug's Life in the Best Spoken Word Album for Children category. She has sang in a number of other roles throughout the years and hopes to release a country album one day.
