People and Us Weekly reported this weekend that Chris Brown and Rihanna were reunited and nursing their cuts and bruises at Diddy's Miami Beach estate. Since then, we've yet to hear a peep from Rihanna. As for Brown, he's been spotted jet-skiing with pals and even got himself tied to a Kardashian in the gossip columns. Not bad for a guy who probably has his hands full with his anger-management homework.

People's inside "source" blabbed that Brown "continues to be reflective, spending time with Rihanna, staying close to home and working on his music."

This Sunday, however, the R&B singer indulged in some self-reflection and reconnected with his estranged girlfriend by going jet-skiing -- without her. Brown was photographed plowing through the waves around Diddy's Star Island estate with a gang of friends.

As for who exactly he's been keeping company with, Khloe Kardashian would like you to know she's not part of Brown's crew. People published a report over the weekend saying that the not-so-famous sister of another not-so-famous person was spotted partying with Brown and Reggie Bush at Miami's Gansevoort South Hotel.

According to Kardashian, she and Bush were there, but not Brown. "The funny part about this alleged 'news' is that I've never met Chris Brown!" wrote Kardashian on her blog, clearing up the mistake.
