(TMZ) - Rihanna and Chris Brown's new romance has already gone to pot. The couple celebrated the Grammys by hitting up a Hollywood nightclub and lighting up what appears to be a joint, TMZ reports.

Chris and Rihanna, who won her 7th Gram last night for her "We Found Love" music video, dropped by Supperclub for a private party. TMZ reports that according to sources inside the venue, the whole place was filled with pot smoke.

And there's this - According to TMZ, Chris was shot driving away from the club with Rihanna in the passenger seat at around 3:20 AM, which would be a big issue if he's driving under the influence of pot - a big issue because he's on probation for beating his passenger to a pulp.
