Rihanna and Drake are not only collaborators but also they have tied for most successful albums of the year so far. Their perspective albums, "ANTI" and "Views" have both been certified double Platinum for sales and streams totaling 2 million. Congrats to both! In other music news, Chaka Khan and her sister have both checked into rehab for addiction to prescription pain medication. Sources say Chaka was touched by friend Princes' death and his addiction to pain medication that she prompted to get clean. Good luck Chaka! You are in our prayers! It's funny because Chaka has a history of drug and alcohol abuse over the years. It hasn't seemed to affect her voice though, I will say that. On the reality TV front, Porsha Williams of "The Real Housewives of Atlanta" has an arrest warrant out. If you recall back in December, Jami Ziegler; an one time associate and employee of Porsha's was beaten down by Williams during a Christmas party while filming the popular reality show. The footage was caught on camera but didn't air until the show's finale. Source say Porsha became angry with Ziegler after she brought an acquaintance to Phaedra's Christmas party that she didn't approve of. Williams chased Ziegler into an alley and went berserk on her. I'm hoping the cameras are catching this and something tells me they are. We will have to see how this all plays out in the media and I'm sure we'll get a glimpse of Porsha's arrest on the upcoming season of "The Real Housewives of Atlanta".
