Is Wladimir Klitschko Divorced?

Wladimir Klitschko and Hayden Panettiere are former fiancés and co-parents.
They first became romantically involved in 2009 and later became engaged. After welcoming Kaya in 2014, they separated again in 2018. Despite ending their romantic relationship, they have continued to share a strong connection through their daughter.
In a 2026 interview, Panettiere said she had an “incredible relationship” with both Klitschko and Kaya and described Klitschko as someone with whom she had a deep friendship.
Their relationship has therefore evolved from romantic partners to co-parents who remain connected for their daughter’s well-being.
Will Wladimir Klitschko Get Custody Of Hayden Panettiere’s Daughter?
Wladimir Klitschko already had full custody of Kaya before Hayden Panettiere’s death.
In 2018, Panettiere agreed to give Klitschko full custody of their daughter. She later explained that she decided because she believed Kaya would have greater stability and support while living with her father in Europe.
Panettiere said the decision was extremely painful but that she believed fighting the arrangement could have negatively affected Kaya. She continued to maintain a relationship with her daughter through visits and communication.
Following Panettiere’s death on August 16, 2026, current reporting indicates that Kaya has been living with Klitschko. However, any new legal guardianship or court proceedings following Panettiere’s death have not been publicly detailed. Therefore, it would be inappropriate to speculate about future legal arrangements.

The family has generally avoided publicly disclosing sensitive details about Kaya’s school, daily routine, or private life.
