Actress Jennifer Love-Hewitt has returned to her musical roots to shoot a racy new promo for her TV series The Client List.

The star sings and dances in director Matthew Rolston's I'm a Woman promo, wearing only black and white lingerie and sky-high stilettos.

And Hewitt has revealed her cover of the standard was produced by American Idol judge Randy Jackson.

In a tweet, she writes, "Thanks to Randy Jackson for doing an amazing job on the song for our promo. It was a dream."

The video, which debuted online on Tuesday (05Feb13), was made to promote season two of The Client List, in which the actress plays a single mom who is forced to turn tricks at a local massage parlour after her husband abandons the family.
