Michelle Dockery has returned to work after what's likely been one of the most difficult periods of her life.

The actress has returned to the set of Good Behavior this week, three months after the heartbreaking death of her fiancé, John Dineen.

She appeared to be in good spirits, wearing a red wig and smiling while filming the new TNT series in North Carolina. At one point, she even shared a laugh with a few other members of the cast and crew.
