Hayden Panettiere has returned to work. The 26-year-old actress sought treatment for postpartum depression in October, 10 months after the birth of her and fiancé Wladamir Klitschko's daughter Kaya and she recently resumed filming on TV show 'Nashville' following her leave of absence. TVLine reports that Hayden, who plays country singer Juliette Barnes on the show, was on set to begin filming episode 14 of season four of the drama series. She is expected to be back on screens in April. Revealing Hayden's decision to seek treatment last year, her spokesperson said: "Hayden is voluntarily seeking professional help at a treatment centre as she is currently battling postpartum depression. She asks that the media respect her privacy during this time." And in a case of life imitating art, Hayden's 'Nashville' character was also suffering with postpartum depression. Executive producer/showrunner Dee Johnson previously insisted she expected Hayden to be back. She said: "It's not the entire season, it's just for now. We've had to make adjustments, but it's not uncommon for shows to have to make such accommodations when real life intervenes."
