Britney - 2 #1 singles and a #1 album. 500k opener.
GaGa - 4 #1 singles and a #17 album. 24k opener.
you are NOT that stupid, which means you ARE a TROLL....... Gaga wasn't even "known" until Just Dance hit big in dec/jan. her album came out in october so try again.... and ever since she's been "known" she's been kicking Britney's sloppy uneducated trailer park self in EVERY measurable factor of success..............
