It is in fact a picture of Rhianna. If you compare the tattoo that you can see on the left side of her neck/shoulder to other pictures of Rhianna, you can tell it's her.
If I remember correctly, I believe that Chris Brown was a victim of abuse himself, not that that exonerates him of any guilt.
And like the week before this happened, I was reading an article in a magazine saying that Rhianna was super-clingy, jealous and possessive over Chris. Again, not saying that she deserved this.
No one deserves to be beaten. Man, woman, child, elderly, every person deserves to be treated with respect. No person should ever have another's hands placed on them in a violent manner without consent. (Some people would consent, some people are strange.)
The only thing that I'm saying is that this wasn't the first sign of this being an unhealthy relationship.
I was listening to the radio the other day and someone said that all the radio stations should play Rhianna's "Take a Bow" over and over again until she takes her own advice.
Sorry this is so scatter-brained, I'm all messed up on cold medication, trying to make it through the day!
