Rain can't stop bad girl Rihanna

Rihanna is the kind of pop star parents have nightmares about: A bubblegum singer who elevates raunch to a high art and crams her teen-friendly songs with X-rated lyrics.

She even has a boyfriend straight from the casting department in the form of controversial RnB singer Chris Brown.

In concert, she ratchets the scandal factor higher yet. Her new tour features pole dancing, microphone fondling, and an endless parade of barely-there evening wear, including at least one costume that initially looks as if it is primarily composed of translucent tissue.
