Britney Spears is sticking to her guns about maintaining control of her life. The popstar is taking career advice from no one, and even walked out of a photo shoot for her own perfume last week. "There was a shoot last week in LA for a new perfume she's coming out with and something happened," reveals an insider. "She got very upset and stormed out of the shoot and wouldn't come back. She is not listening to anyone and doing exactly what she wants. But sometimes she doesn't know best." A rep for the star did not return emails.
