B Spears: Unfit for the new Gong show?

She must have really PO'd her sound engineer.

She is batting below the Mendoza line!

I've spent a lot of time around that business.

I strongly suspect that it wasn't her guys that did this. Unauthorized routing of any signal, especially unprocessed signal, is always grounds for immediate dismissal.

Someone could have hi-jacked her wireless mic feed.
Digital audio signal is also easily split and widely distributed across most concert venues these days.

As I doubt this was a live broadcast. Video post production is the most likely place someone could pull this off anonymously.
