Though police didn't find Justin Bieber in possession of any drugs during their house raid, sources say the singer isn't so squeaky clean.

According to TMZ, the Bieb has developed an addiction to sizzurp and his handlers are urging him to go to rehab. 

The gossip blog says the singer has been regularly drinking "sizzurp" or "lean," which includes codeine and promethazine. He's also said to be abusing prescription pills, including Xanax, as well as alcohol and pot. On the bright side, the sources insist Justin has never used cocaine.
