Rihanna hit the roller coaster yesterday afternoon at Six Flags outside LA. She also bonded with a few furry friends when she wasn't enjoying the rides with her other pals. Elsewhere, Chris Brown was dealing with some "confusion" — the first clip out from tomorrow's appearance on Larry King Live shows him saying he doesn't remember assaulting Rihanna last February. Chris now claims the interview was edited improperly and that "of course" he recalls the incident. Either way, it seems like the interview designed to help Chris's cause is just further complicating his efforts to rehab his image.
