Found this on Youtube and i must say she sounds very bad

This is universally known by even casual fans, and it's also over 7 years old...

 

She was also dancing her ass off right before the song. Here is another performance 100% live and it's amazing <3

 

 

NOT A GIRL

HE ABOUT TO LOSE ME

 

Only time she didn't sing her ballads completely live on tour was with 'Circus'.

At the least she reaches the high note at the end! :D

Yea... well it's so hard to dance and sing,

running around, out of breath.
