Justin Bieber’s paparazzo assault case is still raging on in the courtroom, and now things may have taken a scary turn for the young pop star. There have been reports that The Biebs uses drugs and has been drinking even though he’s not 21, and the paparazzo’s lawyer wants to prove it! So, he’s subpoenaed JB’s friends Lil Twist , Lil Za , Khalil , manager Scooter Braun, and even his trainer Patrick Nilsson. The lawyer wants to show a connection between Justin using marijuana, sizzurp, and booze and him becoming aggressive. However, there have been reports that Justin is on a healthier path now, so maybe there’s some upside there.
