Some crazy stuff went down at the Fashion Rocks after party at New York’s Rainbow Bar last weekend. According to reports, Justin Timberlake had to dive for cover and dodge punches after his bodyguard tried to grab a mobile phone off a fan who sneaked into the VIP area to snap a picture of the singer. All hell broke loose when the girl’s friends stepped in to help her and glasses flew off tables and shattered everywhere. Beyonce, Mariah Carey, Rihanna and Chris Brown all had to duck for cover as well. The divas were supposedly shrieking in horror as their security teams protected them from the flying debris.
