"OK Not to Be OK" is a song by American music producer Marshmello and singer Demi Lovato. It was released on September 10, 2020, via Island Records and Joytime Collective, in partnership with the Hope For The Day suicide prevention movement. The song was later included on the expanded edition of Lovato's seventh studio album Dancing with the Devil... the Art of Starting Over.
The song was teased various times by Marshmello through his social media accounts; shortly prior to its release, in July 2020, he liked fan tweets confirming the track and also captioned an Instagram photo "hello? demi?", before later removing Lovato's name from the caption.
