Chris Brown singer rihanna necklace avalon hollywood

Last night Chris Brown performed at the Avalon in Hollywood, and while ex-girlfriend Rihanna was nowhere to be found, plenty of other ladies, including R&B stars Ciara and Keri Hilson showed up!

Uhh, I know Chris is a great entertainer and all, but you'd think after the whole Rihanna incident (you know, where he bashed her face in and allegedly threatened to kill her?) he would have lost most of his fans...especially young female celebs! Guess not?

What's even more interesting is that Chris just walked into a Los Angeles courtroom for a progress-report hearing...think he was able to sleep off last night's partying in time to look presentable for the judge?
