The 29-year-old 'Ghost Whisperer' star - who split with fiance Ross McCall over Christmas - is back on the set of her hit show, but seems "quiet" and "sad".
A source told People magazine: "She is usually very bubbly, but she is more quiet and seems sad. She usually hangs out with the crew between takes, but now she is only hanging out with her bodyguard."
But no matter how upset she was, friends say Jennifer would never consider taking time off work.
The source said: "She is always so professional. She would never even think to miss a day of work because of personal problems."
Jennifer and the 32-year-old 'Band of Brothers' actor got engaged in November 2007 after two years together. Friends and family were shocked when they announced their relationship was over.
Another source said: "They're both really sad about this. Even their friends are surprised, they seemed really happy."
