FIESTAR is a five member girl group that originally debuted under LOEN Entertainment. They debuted with six members, with former member Cheska leaving the group in 2014. The group had disbanded in 2018 after the members contracts had expired and the members decided not to renew. In 2024, member Cao Lu had gathered enough funds to buy the copyrights of some of their songs. The group reformed in 2024 with a rerelease of their song "You're Pitiful". They signed with a different company and are continuing to make songs as a group, promoting in South Korea and China.
