Hayden Panettiere and Wladimir Klitschko have split up
The actress and the heavyweight champion boxer have decided to call time on their 18-month romance because they couldn`t cope with having a long-distance relationship.
Hayden, 21, lives in the US, while 35-year-old Wladimir - who was raised in the Ukraine - is based in Hamburg, Germany.
A statement from Hayden said: "While we decided to split, we feel great sympathy and respect for each other and will surely stay close friends."
Wladimir added: "We had a great time together. But more and more we realised how difficult it is to maintain a relationship when living on two continents - I cherish Hayden as a person and woman. I`m sure we will stay friends."
Wladimir - whose brother Vitali Klitschko is also a world champion boxer - is currently in training for his heavyweight title unification bout with British fighter David Haye which takes place at the Imtech Arena in Hamburg, Germany, on July 2.
