Actress Jennifer Love Hewitt is returning to the small screen for a new series based on her TV movie "The Client List."

The "I Know What You Did Last Summer" star portrayed a mother forced to turn to prostitution to pay her bills for the 2010 Lifetime network film and it's now set to be extended for a weekly show.

Hewitt begins shooting the program in January (2012) and so the busty brunette has decided to avoid over-indulging during the holidays so she'll be in tip-top shape for her sexy scenes.

She tells, "I will be in lingerie a lot, so I'll be working out. I will not be eating for the holidays."

Hewitt's last regular starring role on a TV series ended in 2010 when "The Ghost Whisperer" was canceled after five seasons.
