Jennifer Love Hewitt is said to be “having a tough time” since her split from fiancé Ross McCall over the holidays. Sources say Hewitt is back to work on the set of her show ‘The Ghost Whisperer’ but says the actress is not her usual “bubbly” self.

“She is usually very bubbly, but she is more quiet and seems sad. She usually hangs out with the crew between takes, but she is only hanging out with her bodyguard.”

Hewitt, 29, and McCall, 32, began dating in 2005. They were engaged in November 2007. People magazine exclusively reported their split earlier this week.
