@X Im not trying to belittle anything that they di in their careers but they didnt do as much in as little time. GGGB came towards the end of her first couple of years and didnt sell 9 million in a few months, it took a while meaning that Gaga still sold more in a short amount of time. Plus The Fame is Gagas first album, she didnt have a huge fanbase to rely on to support her or any other previous singles to back her up. She came out the gate on top and she wont slow down any time soon. It took rhianna 3 albums to sell around 15 million yet gaga sold over 12 million with one album alone and The fame Moster is a seperate body of work which picked up almost six million this year alone. Not to mention Born this way which is being released in a few months
