"Por Favor" is a song by American rapper Pitbull and American girl group Fifth Harmony from the group's self-titled third studio album. The song was written by Pitbull, Madison Love, Sermstyle and Philip Kembo, and produced by the latter two. Additional writing credits were also given to Usher, Alicia Keys, Jermaine Dupri, Adonis Shropshire and Manuel Seal, as it contains a sample from the 2004 single "My Boo" by Usher and Keys, as well as Barry White since the latter song incorporated a melody from the 1977 song "He's All I've Got" by American female vocal trio Love Unlimited. The song was released on October 27, 2017, in two versions; a Spanish version, in which Lauren Jauregui and Ally Brooke are the main two contributors from the group heard on the song, and a Spanglish version, where all four members can be heard. The Spanglish version has been performed at the 2017 Latin American Music Awards, on the finale of Dancing with the Stars and on Showtime at the Apollo. Shortly after the single's release the Spanglish version was included on the Spotify re-release of the album, thus becoming its third official single and the final single released by the group prior to their indefinite hiatus, which began in 2018.
The original version of the song was also intended to be included on Pitbull's eleventh studio album Libertad 548 (released September 27, 2019), but it did not make the final tracklist. An additional full-English extended remix to the song, which was used for live performances by the artists, was released to DJ record pools and radios for airplay.
