Wonder what it would be like to shoot a commercial right on the Hollywood sign? For Gwen Stefani, this type of fantasy recently became a reality, as the iconic landmark became the backdrop for an upcoming L'Oréal ad. Using words like "unbelievable," "breathtaking," "exciting," and "surreal," Gwen seems slightly bewildered and genuinely grateful to have such an experience. Catch her first commercial for L'Oréal here, and watch the video below to see Gwen — clad in a chic black tuxedo and bouncy, sexy waves à la Marilyn Monroe — strut her stuff. Hooray for Hollywood, indeed.
