Though he once sang "light it up and take a puff, pass it to me now," it's likely that Nelly is regretting his most recent toke. The rapper's tour bus was pulled over in Tennessee on Saturday, April 11, according to TMZ.

The bus was originally stopped for not having the proper Department of Transportation sticker, but when cops smelled weed, they decided to search the vehicle.

Police told TMZ that they found a bag that tested positive for meth and they also found a small amount of marijuana aboard the bus. Cops also found several guns, presumably without the proper permits. Nelly's lawyer also told Us Weekly that there was allegedly a small amount of MDMA that was confiscated.

Nelly, 40, was booked on felony marijuana possession charges and his passenger Brian Jones was arrested for possession of handguns.

The "Country Grammar" emcee's lawyer told Us in a statement: "Nelly was one of several individuals that was on a tour bus that was stopped and searched while traveling through Tennessee. In fact, there had been 15-20 people that had access to the bus prior to the stop. Allegedly, a small quantity of contraband (MDMA aka Molly or Ecstasy) was discovered during the routine search. We are extremely confident that when the facts come out, Nelly will not be associated with the contraband that was allegedly discovered."
