An ABC rep declined to comment, but sources confirm that the actress reported back to the set on Friday to begin work on Season 4’s 14th episode, which is slated to air in April. (Nashville returns from its midseason break on March 16).
Panettiere left the series in early October just as Episode 9 was about to start production. Her character, Juliette — who in an eerie parallel was also battling postpartum depression — was last seen in the Nov. 18 episode.
