There could be a reason that Rihanna wasn’t with Chris Brown in court Friday — sources tell us he’s been “hanging out with a beautiful New York waitress.” We hear Brown hit it off with stunning server Karizma Ramirez at Finale when he visited the club Easter weekend. A source said, “They hit it off and headed out together. They also spent Easter Sunday together.” Despite this, Brown said he and Rihanna are still together during a “Today” interview that aired April 1. On Friday, Brown sat in court as lawyer Mark Geragos met with an LA County Superior Court judge behind closed doors in the probation-violation case. The judge ordered Brown back June 10 because lawyers need more time for “additional discovery.” Prosecutors accuse Brown of not completing 180 days of community labor ordered when he pleaded guilty to felony assault in his infamous Rihanna beating. Geragos has argued that the prosecutor’s wrong and Brown’s been “tortured” during his probation. Brown’s mother was in court Friday, but Rihanna, who attended his last court date, was not.
