Panettiere's social media accounts had been radio silent over the past 10 months. Her last post, on Feb. 7, was of her 5-year-old daughter, Kaya, whom she shares with ex-fiance, pro boxer Wladimir Klitschko.

The unannounced Twitter break coincided with the actress' personal struggles regarding her current boyfriend Brian Hickerson.

In May, Hickerson was charged with domestic violence and was later ordered by a judge to stay away from Panettiere. The case was ultimately dismissed in September and, soon after, the two started dating again.

Most recently, the pair spent Thanksgiving together as seen in photos posted to Hickerson's Instagram.
