More trouble in Celebrity Drugville: Rapper Nelly was detained in Texas Wednesday night after police officers uncovered a bounty of drugs and a loaded gun on his tour bus.

TMZ reports that the 37-year-old “Hot in Herre” singer was passing through the Sierra Blanca border patrol — the same tricky checkpoint 30 miles north of Mexico where Fiona Apple, Willie Nelson, Armie Hammer and Snoop Dogg also got drug-busted — when a police canine indicated that there were drugs aboard the vehicle. Law enforcement sources then found a whopping stash of illegal substances, including 36 small bags of heroin, 10 pounds of marijuana and a .45 caliber pistol.

All seven passengers of the tour bus were detained. Nelly (whose real name is Cornell Iral Haynes, Jr.) and five others were released after passenger Brian Keith Jones claimed that he was in sole possession of the drugs and gun aboard. The rapper is set to perform in Austin, Texas, next month as part of the COTA Austin fan Fest with peers Flo Rida and Enrique Iglesias.
