According to E! Online, Chris Brown and Karrueche Tran are on again! Reportedly, the couple spend the Memorial Day weekend together in Las Vegas. Karrueche was allegedly seen rubbing suntan lotion on Chris' chest and danced along while he gave his impromptu performance at Palms Casino Resort with 9Group. Well, I must say this is an interesting development in the love triangle, but I am wondering what is going through Rihanna’s mind at the moment. At this point, I really don’t think Chris knows what he wants and is not really to settle-down, but it would not surprise me if he got back together with Rihanna again.
