Justin Bieber

Moroney says she would pass out, throw up and die if she met him!

The filing claims their song is too similar to be original work.

They beat out songs by Brothers Osborne, Lady A, Little Big Town and Old Dominion.

They're nominated at the big awards show, too.

In a now-deleted post, Bieber poked fun at Taylor Swift's viral video from after her laser eye surgery.
