It is with great sadness but amazing praise that we announce the news that Hayden Panettiere has entered rehab to deal with her Postpartum Depression. The "Nashville" star welcomed daughter Kaya, who will be one in December with fiance Wladimir Klitschko, a professional boxer. Hayden, 26 admitted that she was struggling but took to social media on October 10th to share that she was feeling a lot better. Today, that took another turn as her rep told E! on the actress/singers behalf: "Hayden Panettiere is voluntarily seeking professional help at a treatment center as she is currently battling postpartum depression. She asks that the media respect her privacy during this time."
