Justin Bieber's rapper pal Lil Za has been charged with two counts of felony drug possession over substances found in a police raid on Biebs' house.

The 20-year-old - whose real name is Xavier Smith - was arrested on 14 January after officers apparently discovered tablets and powder in his room at the mansion in Calabasas, near LA.

He has now been accused of possessing of MDMA (ecstasy) and prescription painkiller oxycodone, which is a restricted substance.

According to E! News he is also reportedly facing a third felony charge over an incident in which he is alleged to have vandalized a telephone at the Los Angeles County Sheriff’s jail.

We told you yesterday how JB's toxicology report relating to his arrest on suspicion of driving while under the influence (DUI) had been released.

He also turned himself in to police earlier in the week over an alleged attack on a limo driver in Toronto.
