Rapper Nelly was detained last night in Texas while police officers searched his tour bus and found massive amounts of weed, HEROIN, and a gun. 

While rolling through border patrol checkpoint in Sierra Blanca cops pulled the bus over and after performing a search, they found 36 small baggies of heroin (totaling .64 ounces) and over TEN POUNDS of marijuana inside a large green duffel bag (an amount roughly the size of a large bed pillow). Cops also say they found a loaded .45 caliber pistol.
