"The Knife" marks Aquilina's first new single since last year's Ghost World album, and is co-produced by Aquilina and Marcus Andersson (SOPHIE, Ashnikko).

Aquilina says her new release is "the song that introduces people to a brand new side of me."

On top of releasing her own music, Aquilina is an accomplished songwriter, having recently received three songwriting credits and a couple of producing credits on Demi Lovato's latest record, Dancing with the Devil... the Art of Starting Over.

Lauren Aquilina's "The Knife" single is out now.
