Jewel has signed a worldwide deal with L'Oréal's line of Feria hair-color products to be part of a new ad campaign titled "Colour of Your Voice." The first TV ad debuts Sunday (March 14) in the United States.

The commercial will feature Jewel singing "Yes U Can," a cut from her latest Atlantic Records album, "0304." The singer/songwriter is currently on a U.S. tour in support of the album.

Meanwhile, Jewel will have a role in the feature film "Wave," about a mother who attempts to reconnect with her adult son after she gets out of jail. Jewel, who will play the girlfriend of the son, is co-producing the movie through her Gravitas Entertainment company. Goldie Hawn's Clearlight Productions is also on board to produce the film, which is expected for release this year or next.
