Chris Brown partying with Khloe Kardashian?

As we reported previously, Chris Brown is in Miami allegedly back with Rihanna, but a new report says he’s also hitting the party circuit, with Khloe Kardashian.

“Chris Brown was hanging with the group after stepping out of a car with cutie Khloe Kardashian,” a witness told People Magazine.

“Then he hung with the group and had a great time enjoying his friends poolside at Plunge, the romantic rooftop bar area of Ganesvoort South,”

Others in the group included rappers Young Jeezy and Plies, and football player Reggie Bush.

Khloe Kardashian has denied the rumors, writing on her blog that “So I woke up this morning to a ridiculous amount of missed calls and news EVERYWHERE that I had been spotted out and about in Miami with Chris Brown…The funny part about this alleged ‘news’ is that I’ve never even met Chris Brown!”

In related news, Rihanna is facing a backlash from fans for reuniting with Brown. Forums and Rihanna fan groups have called Rihanna’s decision to return to Brown disgusting, and say that it gives the wrong message on domestic violence.
