"Heroes" actress Hayden Panettiere, 22, and Ukrainian boxing champ Wladimir Klitschko, 35, knocked out their 5-month relationship in May. The two clearly decided to take the high road. "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 told People at the time. "We had a great time together, but it's not that easy to manage a relationship between two continents," Klitschko said separately.
