Rihanna is sure not feeling what the other artists are feeling when Chris Brown was at the Grammys performing and even won one award.

It was reported that Rihanna threw out an advance birthday party for herself last Monday. A hundred of her closest friends came and in attendance as well was none other than Chris Brown, the very same man who for one night distorted her pretty face 3 years ago.

For this to have happened, it is safe to say that this two have really come a long way.

From the eve of the incident, to Chris’ sentencing and being not allowed to go near Riri, to wild speculations regarding their tweets up to being friends again?

Sources who are present at the party confirmed that indeed Chris Brown was at the party and the two appeared to be friendly to each other.

Well, if there is one person who should know when to let what all happened be just “water under the bridge” now, it should be none other than Rihanna.
