Rihanna seems to be the hottest topic in celebville at the moment, so there's no surprise that her recent trip to the Hollywood Hills caused a massive stir in the glitzy neighbourhood.After cancelling her 21st birthday bash last week.

The battered star decided that she wasn't going to let Chris Brown stop her having the birthday party she deserved, so she hit the cinema before heading to the trendy Hollywood Hills to rave the night away.A friend of the singer told Heat; "

People were scrambling at her feet to make sure her every wish was granted. She was a bit shy at first and kept her glasses on most of the night. But once she saw her old crew and got used to being out, she really got into it. She was even dancing!"
