Don't mess with Rihanna! After coming under fire with the Parent Television Council for the violence in her recent "Man Down" video, the sexy singer unleashed via Twitter. She Tweeted:

    "I'm a 23 year old rockstar with NO KIDS! What's up with everybody wantin me to be a parent? I'm just a girl, I can only be your/our voice! We have the freedom to make art, LET US! Its your job to make sure they dont turn out like US. U can't hide your kids from society, or they'll never learn how to adapt! This is the REAL WORLD."


RiRi's Man Down video has been criticized by the PTC for certain violent scenes ... one in particular of RiRi gunning down a rapist in a crowded train station. The PTC says the scene shows a "cold, calculated execution of murder."
