The much-talked about relationship between Rihanna and Leonardo DiCaprio may be entirely made up by rumors, but if it does end up being true, the bad gal’s ex Chris Brown is giving his blessing. Of course, no one ask this of Brown, but it is pretty fulfilling hearing the singer admit that Rih is making an upgrade from himself. In an interview with Hot 97 Radio over the weekend, the “Loyal” crooner admitted he did not call his ex girlfriend on her birthday (which she celebrated Friday) because his girl Karrueche Tran would have “slapped” him. However, he does admit that he’s finally at a point of being cool with her and whatever she’s doing in her life and career.
