Meanwhile, a judge today lifted the restraining order on Rihanna's ex boyfriend Chris Brown
It was replaced by a level on order - meaning Brown and Rihanna can have contact as long as he does not harass, annoy, or molest her.
Rihanna was not in court but her attorney Donald Etra told the judge she had no objection to the new order.
