If Gwen Stefani did a beauty commercial (which she now has as L'Oréal's most recently named spokesperson), what do you think it would look like? If lots of red lipstick and some Gwen tunage running in the background come to mind, you'd be right. Check out Gwen showing off her famous signature red lipstick as she sports funky menswear and splashes red paint on the wall with "Hollaback Girl" playing in the background. I might add: only Gwen can deliver L'Oréal's slogan, "Because we're worth it," with such cool attitude.
