Gwen Stefani has said she loves getting the opportunity to wear fun fancy dress as part of her career.

The former No Doubt frontwoman was signed up this week as a new face for L'Oreal Paris, joining the likes of Eva Longoria and Beyonce Knowles to promote the brand's beauty products.

She said she can't wait to begin and is especially looking forward to the costumes.

"I can't believe I get to be one of the L'Oreal Paris girls. I love playing dress up, on stage or shooting videos, it's always been one of my favorite parts of being in a band," Stefani commented.

One of her most famous outfits is surely the cheerleader fancy dress costume she wore in the video for the single Hollaback Girl.

Courtney Love had criticised Stefani for her image in Seventeen magazine, so she responded with an in-your-face song insisting that she isn't one of the good girls.
