It's her timbre, tone and way of speaking in that audio, and i don't care if you don't believe it, you can have Britney telling you it's her and you won't believe it....is so obvious is her.
And ?what if it's real of course it would be messy and off -key, she wasn't even making an effort to sing, just words coming out of her mouth
Katy Perry makes the effort to sing and this is the result
And again I ask for receipts past a youtube user saying that's her mic feed.
Like HBO would give him the mic feed, and she wasnt even lip synching during that tour.
Katy is always a miss and the poll speaks for it's self so lets not. Britney most of the time is on key which Katy fails tremendously at. It's pretty embarrassing when you have a strong voice yet a woman who smokes and doesn't take care of her voice and hasn't had any vocal training still sings way better than you.
