Just hours before Britney put herself in the running to be Mr. Clean's stunt double, the pop party mom told one huge bald-faced lie to a photog about ever-changing hair.

As Britney trekked through LAX Friday afternoon, following her post-one-day-in-rehab commercial flight from Miami, a photog commented on Brit's new hair color, saying "I love the brown hair." In true Pinocchian form, Britney replied, "Thanks, I think I'm going to keep it this way," as her nose grows.

That night, Brit found her way into a hair salon in Tarzana, and then to a tattoo parlor in Sherman Oaks, where KABC-TV 7 in L.A. caught the Vin Diesel wannabe. For the full video of Brit's bald visit, click here.
