Jennifer Love Hewitt puts unbuttons her shirt,loses her skirt and gets slinky with half a dozen guys in anew video to promote her new TV series, “The Client List.” Who knew she could be this hot?

“The Client List,” which will appear on the Lifetime Network, is based on a real life prostitution scandal in Odessa, TX, in which a mother-of-three turned to prostitution to make ends meet. It became a Lifetime movie.

Although the subject will be the same, the series will not follow the movie, the network said. Hewitt starred in the movie and will reprise her role in the series. Colin Egglesfield, Cybill Shepherd and Naturi Naughton will co-star.

Shepherd will play Hewitt’s mother, and Loretta Devine will play the owner of the massage parlor and brothel that was the focus of the scandal.

To promote the show, the 32-year-old actress sings and dances to “Big Spender,” written by Cy Coleman and Dorothy Fields for the Broadway musical Sweet Charity in 1966. UK singer Shirley Bassey made it a hit.

The video opens with Hewitt walking down a corridor, seemingly in a brothel. She starts to unbutton her blouse and flashes her pink and black lace bra as the scene opens up to a stage. The next thing you know she’s surrounded by half-dressed men.

The series will debut in March. Check out the video below.
