Formed by Simon Cowell in 2016, the band consisted of Brandon Arreaga, Edwin Honoret, Austin Porter and Zion Kuwonu.

The members of PrettyMuch were pursuing solo careers until Syco Music founder Simon Cowell and former label president Sonny Takhar merged them into a group.

[2][3] Since 2016, the members of PrettyMuch have been based in Los Angeles where they have shared a home since March 18, 2016, in which they have worked on their dancing skills in addition to recording their debut EP.

Directed by Emil Nava, it depicts the members dancing and jumping over each other in empty alleyways, along with scenes from a road trip the group had taken.

[10] PrettyMuch performed "Would You Mind" on MTV's Total Request Live in October 2017 and released their second single, "Teacher".

Their second single of 2019, "Phases," was released on April 26, alongside a music video featuring model Justine Mae Biticon.

[18] On July 11, PrettyMuch kicked off their FOMO Tour with opening act Kenzie Ziegler in Dallas, Texas.

[19] On November 22, PrettyMuch released INTL:EP, which features "Me Necesita," a collaboration with Latin-American boy band CNCO, and three other songs, with guest vocals from Luísa Sonza, NCT Dream, and Iñigo Pascual.

[23] They began teasing their comeback to releasing music on their social media, as well as posting a countdown on their website to January 22, 2021.

[24] On January 17, 2021, the band revealed that a new single was set to be released that week, posting the cover art with the title hidden by asterisks (stars).

[27] The EP was released a week later on January 29, along with a music video for the song "Parking Spot" featuring actress and model Alexia Castillo.

The deluxe EP included "Corpus Christi," a song written mainly by Brandon Arreaga featuring a production credit from Lido, and "Smackables," the long-awaited title track teased by the band in various YouTube videos throughout 2020.

The party consisted of the band doing short commentaries on three songs ("Free," "Lonely," and "Corpus Christi") and playing them for fans, performing three of the songs off the complete Smackables EP ("Stars," "Parking Spot," and "Smackables"), and a special premiere of the "Corpus Christi" music video.

[34] On October 7, 2022, PRETTYMUCH announced that Nick Mara is leaving the band and the group is continuing to make music as a four-piece.

Prior to the audition, Porter had a solo career, having released a pop album titled One Love in 2013[39] and made an unreleased rap EP.
