Apparently the programme was edited heavily, it appears that Joan Rivers is asking Ciara about Ri's BRIT outfit and Ciara seemingly, randomly replies that the last time she ran into Rihanna at a party she wasn't very pleasant to her. I think Joan Rivers actually asked her something else (i.e something more direct like 'what's she like?') and this was edited out. Anyhow, Joan Rivers then wrapped that bit up by saying something like 'She's a b*tch, next' (referring to Rihanna). And thus Twitter stupidity ensued.
