There was an act which was previewed to have been told to "get off" by Alesha - anyone know which act this was?

Was it the same act who threw something (a microphone?) at David? They were also previewed but not shown.

We will never know now.

Someone asked Alesha on twitter and basically she was defending amanda as someone came on and started having a go her, so Alesha stepped in and defended amanda!
Here's what Alesha said:

@AleshaOfficial: @Official_Ellis #getoffthestage gate! Someone was very rude to Amanda, I then had a 'forgot I was on tv moment!!!' lol That's it! 😁👍

Remember they done the same on X Factor auditions. Showed a clip of guest judge Anastacia hysterically crying but never showed the full thing. Its clearly to manipulate viewers into staying. Show 3 seconds of kick off for the next episode but the full clip is probably nothing nowhere near as bad.

I really wanted to see that, was it not shown on BGMT?

That reminds me of Kelly Rowland saying "show us what you've got!" on those X Factor 2011 previews and we never saw what it was.
