“Boo’d Up” is the debut commercial single by singer Ella Mai from her third extended play, Ready. Serving as the lead single for the EP, the song peaked number six on the Billboard Hot 100 in the United States. The song was written by Mai, Joelle James, Dijon “DJ Mustard” McFarlane and Larrance Dopson of 1500 or Nothin’, and produced by the latter two.

Joelle James first wrote “Boo’d Up” in 2014 originally for herself. She later looked for an artist to give the song to, eventually giving it to Ella Mai after feeling that “synergy of it would be perfect for her.”

Mai originally released the song in February 2017 as part of the Ready EP. “Boo’d Up” rose in popularity on social media as well as in nightclubs over the next few months. After Mai served as the opening act on Kehlani’s tour, her music reached a bigger audience and the song grew on radio airplay in the spring of 2018. The song became her first top ten song in the US in the following month, deeming it her “breakthrough hit”. Rolling Stone wrote that the single is “one of the biggest singles by a breakout female R&B singer in the past 10 years.”

Fetty Wap released a remix of the song in June 2018. Rapper Plies performed with the song at one of his show in May. In support of the song and the commercial success, Mai announced a concert tour titled the Boo’d Up Tour in the US during the month of August.
