I have seperated the two stories, as it was two different situations, and I have opinions on both.

Different reports on different websites have their version of confirmation that the woman in question is Chris Brown's girlfriend Rihanna, and that he suffered bruising and bite marks. At face value, it sounds like an arguement that got out of hand.
Interesting to see how the real media handles it, as TMZ and Dlisted are reporting that it is Rihanna, while mainstream media is reporting that the name has not been released.
