Chris Brown is in hot water on allegations that he faked his community service, and TMZ reports that he showed up at court today to plead his case with a notable fellow celeb: Rihanna. It was, of course, his assault of her in 2009 that got him on probation to begin with. Did the move sway the judge? Too early to tell. The judge says he needs more time to review the DA's evidence, and he ordered Brown to check in with his probation officer in the next 48 hours to address the allegations. Incidents like this aren't helping his case. Rihanna recently dished to Rolling Stone on why she's back together with Brown.
