It's not a preview it's just the bg video on her website. This is fanmade.

Whoops, I thought it was real it was posted on thelavalizard.com as her official preview?

That Qween always gets it wrong.

Trent always has the wrong tea.

**** you and everything you stand for,for doing this **** to me

NNNN MY HEART DROPPED

**** You

MessT.
It's clearly the background video dubbed over.

Fanmade. The one who posted it is doing the most with that fake vevo tag.

The title literally says fan made.

I was so confused, I thought she re-uploaded it from Vevo.
