Rapper Nelly is making it crystal clear that he had no idea his bus was carrying heroin when it was searched by Sierra Blanca police in Texas this week. Authorities seized 10 pounds of weed, a loaded .45 caliber pistol and 36 baggies of heroin after a surprise drug bust on the tour bus.

According to TMZ.com, passenger Brian Keith Jones admitted the drugs and weapon were both his and was subsequently arrested on the scene. Nelly said in a statement, "It is my understanding a member of my staff made an unfortunate decision to bring unlawful materials onto our tour bus that resulted in his arrest this morning." He added, "Neither I nor anyone else on the tour bus was aware of his decision to bring these on board. Law enforcement officials did not press charges against anyone other than that individual." Strangely, Nelly still maintains that the drugs were in fact Molly, aka pure ecstasy, despite law enforcement sources confirming that it was most certainly heroin after field tests.

The rapper and his crew were the latest stars to be busted at the checkpoint in Texas, with Willie Nelson famously stopped in 2010 and found to be in possession of six ounces of marijuana. It didn't come as a huge surprise given the country star is a long-time advocate of the drug, though perhaps more surprising was actor Armie Hammer's arrest for weed, marijuana cookies and a brownie.
