Helicopters and police officers were called in to help control the scene outside of singer Tank [remember him?] and Tyrese’s joint birthday party at MyHouse on Sunday. The chaos outside of the nightclub was most likely the result of birthday boy Tyrese and Diddy dishing the party’s location out on Twitter. Along with the LAPD, the event also brought out Rihanna and Chris Brown’s stunt double Matt Kemp, Ray J and Snoop Dogg.
