Panettiere is best known for her roles on the NBC series Heroes, which ran from 2006 to 2010, and the ABC/CMT musical drama series Nashville, which ran from 2012 to 2018. 

In 2009, she started dating Ukranian boxing champ Klitschko and after a brief breakup, they became engaged in 2013.

They welcomed their daughter on December 9, 2014.

However, the actress suffered from postpartum depression so severe that she voluntarily checked herself into a facility for in-patient treatment.

She sought further treatment in 2016.

Panettiere and Klitschko split in 2018 shortly after the end of her TV show Nashville.

Last year, a source told People that Panettiere has been living apart from her daughter for the past two years.

The insider explained to the outlet: ‘Hayden has gone through changes since she had Kaya, and while some were not perfect, others have helped her grow.

‘She is trying to feel good about herself, her life, and how she wants to go forward.’

At the time, a lawyer for Panettiere confirmed to People that the actress and her daughter still see each other regularly.
