But Brown, 23, clearly didn't spend the morning after with RiRi -- he was in court Thursday for a progress hearing stemming from the 2009 Rihanna assault case, where he was granted permission to travel abroad for an overseas tour, but must remain on supervised probation and return to court for an update on the progress of his probation after he completes his overseas tour.
