Jennifer Love Hewitt has revealed that she cannot watch her hit TV show Ghost Whisperer.

The actress plays Melinda Gordon, a young woman who is able to communicate with the dead, on the CBS series. However, she refuses to watch back her performances because she gets too emotional when she does so.

"I can't - I cry every time I watch it. It kills me," Jennifer told WENN. "I cried for the entire shooting of pilot. I am very moved by it."

Ghost Whisperer returns to CBS for a third season next month.
