lol... dragging Bey is SOOOOOOOOOOOOOOO easy... and TBH.... Rihanna won this one BY FAR... mainly coz Rihanna DID sell much more than Beyonce... BOTH albums and Singles.
I couldn't @ Gaga stans coming to defend Bey. Their labels did a smart thing pairing them up and making them seem like "friends" (do they even talk about eachother after Telephone?) at the beggining of Gaga's major success, both benefited from stans who bought it.
