No it isn't lol. It's surprisingly easy to extract the mic feed from performances. See, most of TV and live performances use Dolby 5.1 audio. All you need to do is mute all the other channels and get the mic one.

This is a live feed of her singing along to a prerecorded track. They usually turn her mic way way way low, until the song ends then yank it way back up for her speeches. The audience is meant to hear her breathing and punctuations along with snippets of her strongest vocal abilities. This is very common among artists who dance as well as sing. Britney does not have strong vocals, smoking cigarettes have not helped either.
I know it's fake but this is hilarious af
