R&B star Rihanna has vowed never to strip off for a photo shoot - because her mother would be outraged.

The Barbadian singer - who is reportedly dating Hollywood actor Josh Hartnett - is keen to keep her image clean, despite giving her latest album the provocative title Good Girl Gone Bad.

She says, "I'm only 19. My mother would kill me if I did!"
