LPG (엘피지) was a girl group under AquArgo Entertainment. They orignally debuted as four members on August 10, 2005 with their first studio album Long Pretty Girls. Over the years, the group saw three generations of members, thus ending with nineteen current or former members at the time of their disbandment sometime in 2016. Their name, an acronym for “Lovely Pretty Girls,” was chosen because several of the members were pageant participants, and two of them even were in the Miss Korea pageant. The group's final lineup consisted of four members: Jiwon, Riwon, Songha, and Jieun.
