Nothing helps console a breakheart heart like diving into your work.

And that is exactly what Jennifer Love Hewitt was doing today as she prepared to film scenes on the Los Angeles set of Ghost Whisperer.

Despite her pleasant demeanor, the actress is reportedly “having a tough time” in the wake of her breakup with fiancé Ross McCall.

A source tells People mag: “She is usually very bubbly, but she is more quiet and seems sad. She usually hangs out with the crew between takes, but [Tuesday] she is only hanging out with her bodyguard.”

While J.Love is a little down on her luck in her personal life, she’s on her game when it comes to her career. The insider adds: “She is always so professional. She would never even think to miss a day of work because of personal problems.”
