The lead single off the Birds of Prey (Original Motion Picture Soundtrack), “Diamonds,” is a collaboration between American rapper Megan Thee Stallion and singer Normani. As the song title suggests, the song is about diamonds and it being “a girl’s best friend.”

On December 17, 2019, co-writer Kameron Glasper confirmed the existence of the collaboration via an Instagram story. A set of photos from the unreleased music video were posted on December 21st. Weeks later — on 8 January, 2020 — the single art was unveiled and the song was released later on January 10, 2020.
