Here, Britney combines metaphors of high school slumber party activities with tales of her much more adult night together with her lover. Cause we got them candles hanging Hanging from the ceiling low We use our bodies to make our own videos Put on our music that makes us go f--king crazy, go Go crazy, go Like a slumber party Both activities involve candles, cameras and moving to the music, but while the more innocent slumber party is about dancing and home movies, Britney and her partner are engaging in fornication and sex tapes.

The sultry reggae-pop track was co-written by Justin Tranter and Julia Michaels (the duo that penned Justin Bieber's "Sorry.")

Britney said in a video track by track: "'Slumber Party' is really cool because it's got a Jamaican feel, it's really laid back. I think a lot of girls are gonna have a lot of sleepovers to this song, it's definitely a song you wanna take you and your girlfriends go out and just have a great time – eat a lot of pizza and talk about boys and just be really naughty."
