Rihanna sent her vocals on March 23, 2020, just four days before the release of Partymobile
. Up until that point, the song featured placeholder vocals from PND's girlfriend. "You're a young kid waiting for that present, you wake up, and it's just there," co-producer NinetyFour told Rolling Stone
of his and fellow producer Bizness Boi's choice not to ask PND to send over a preview of the final "Believe It" ahead of its release.
