Rihanna's tour buses were stopped at the border of Michigan and Canada, and it's not because they wanted an autograph. Ten buses were stopped at the border, and when the police boarded one of them they smelled marijuana, according to TMZ. They brought in drug dogs, who went straight to one passenger in possession of a small amount of weed. He was apparently only given a civil penalty.
The amount of marijuana the passenger was found with (or the identity of the passenger) have not been revealed. Rihanna herself wasn't on any of the buses. She was probably with the rest of the weed, because we all know that RiRi ain't touring without some party substances. We all know she's capable of getting down--just check out the linked post below. Either way, she's lucky she wasn't busted and was able to continue touring.
