“Slumber Party” is a song recorded by American singer Britney Spears for her ninth studio album, Glory (2016). It was written by Mattias Larsson, Robin Fredriksson, Julia Michaels and Justin Tranter, and produced by Mattman & Robin. The duo was also responsible for vocal production along with Mischke. The song was released as the second single from the album, on November 16, 2016, featuring vocals from American singer Tinashe in a remix version. It was sent to US contemporary hit radio on November 22, 2016. A reggae-pop and R&B track, “Slumber Party” features brass, marimba, “syncopated synths”, percussion and a horn section in its instrumentation.
Lyrically, the song is defined as an ode to fornication and making sex tapes, where Spears uses double entendre, while evoking one-night stands, the ritual of sleepovers with friends and the teenage game of seven minutes in heaven.
