Hayden Panettiere is receiving treatment 10 months after giving birth to her daughter, Kaya Evdokia. She "is voluntarily seeking professional help at a treatment center as she is currently battling postpartum depression," her rep tells People. The 26-year-old opened up about the condition while discussing her Nashville character's battle with postpartum depression in an interview last month. "I can very much relate. It's something a lot of women experience," she said. "It's really painful and it's really scary." She continued, "It's something that needs to be talked about. Women need to know that they're not alone." (More Hayden Panettiere stories.)
