Legendary singer Willie Nelson was busted over the weekend in Texas for possession of six ounces of marijuana. Wait ... Willie Nelson smokes pot? Who knew.

Nelson’s tour bus pulled into a routine checkpoint in Sierra Blanca, Tex. and in an astonishing feat of law enforcement, an officer noticed a familiar herb smell.

Hudspeth County Sheriff Arvin West said: “It’s kind of surprising, but I mean we treat him like anybody else." And by surprising, he probably means not at all.

As much of a joke as this sounds like, a criminal defense attorney in Austin says six ounces of pot could get Willie six months minimum and up to two years.

But Bruce Margolin, director of the L.A. chapter of NORML, thinks he has a defense that could spring the 77-year-old crooner by tracing the weed to Cali.

Specifically, Nelson can claim he forgot the California-grown pot was on the bus. The Golden State is cool with medicinal marijuana, after all. Stay tuned.
