i can't at people saying Gaga cuz of that video where she's puking while singing TEOG.

they play back track at that part always, like on every concert, that's something we all know, cuz she's doing the choreo with Mark and he's like spinning her and ****, but the rest of the song and the other songs are being performed live. y'll are just pressed.
Britney is my answer tho, but i'm not even judging her. it's not like that's something new.
