[Britney]布兰妮在S&m有真唱吧 看了歌迷拍摄的

是的。。却是是有真唱的。。但是背景音乐太大了。。盖住了一些发音。。so。。。
下面不说了。。。。

honestly i don't know why she doesn't sing live. she has a pretty good boice from what i've heard. My boyfriend is a major fan and dragged me to her concert in 09 and she only sang one song live "you oughta know" from alannis (can't spell her name). I was surprised she sang it and surprised it sounded good too, i don't know why she doesn't use that voice more often.
