Unfortunately it's already all over the web and the damage has been done. The post on tumblr has over 40,000 notes.

It must have taken a lot of time to create so many alter accounts.

really? because it has over 40k notes on tumblr, katy ha career is over!!!!1!

Too late

Would somebody explain me what happened cuz I wasn't aware of it.

hm

lmaooo......

I don't get the fuss. She performed live after the lipped one was stopped.

Nrj is a french website they probably used google translate so don't judge them

Drag it.

Wait, do people actually think she was lip-synching? Say what you want about her vocals, but she doesn't lip-synch. And it was really obvious from the video that she wasn't trying to..no one could be that horrible at it.

Hehehe

She was singing completely different words So ridiculous. If people watch just the beginning and think she was honestly trying to lip sync, they're stupid.

They accidentally started playing the version with vocals and Katy didn't realize, so she was actually singing in her mic. Then some guy came on stage during the performance, stopped everything, apologized, and they restarted and Katy did her usual not-great performance of Roar.

She'll never go back there, that was humiliating
