Some relationships are meant to go the distance, but that wasn't the case for Hayden Panettiere and Wladmir Klitschko.

After two years of dating, the Scream 4 star and the Ukrainian heavyweight boxing champion have called it quits, Us Weekly can confirm.

"We had great time together but it's not that easy to manage a relationship between two continents," Klitschko, 35, explains. "I have a lot of respect for Hayden as a person and as a friend and I believe we'll keep our friendship even after the separation."

The Heroes alum, 21, shares her ex's sentiments. "Even though we've decided splitting up is best for both of us, we have an amazing amount of love and respect for each other and remain very close friends," Panettiere tells Us.
