We nominate Chris Brown and Rihanna for the Very Worst Grammy Night Date...These two were the cutest things. They spent ages denying their relationship. We couldn't help wondering if J Hova's gospel for his proteges included a no-boyfriends passage but then we learnt that Jay-Z was actually screening her dates. Meanwhile, Chris and Rihanna kept being snapped in more-than-friendly situations. She said they were like siblings and he declared it was just that they "had the worst luck with pictures." But then they could not hold back anymore and there was all-out PDAs. Now a public bust-up of her doll-like face and a possible prison sentence for him! Then there are those nasty, viral rumors about the cause of the car fight. Good relationship gone bad, seriously bad.
