Twins are a Hong Kong Cantopop duo that was created in the summer of 2001 by Emperor Entertainment Group (EEG). Twins are made up of two girls, Charlene Choi (蔡卓妍) and Gillian Chung (鍾欣潼). They are a popular group in Hong Kong and a top band in mainland China. Their fanbase have included Taiwan, Japan, Singapore, Thailand, Malaysia, Canada, Australia, United States, Vietnam and Philippines. Their music was generally targeted at young teens, but in 2004 they began to attract a wider audience by venturing into different styles of music. In February 2008 the duo temporarily separated after the Edison Chen photo scandal involving Gillian Chung. The group reunited two years later in 2010.
Since 2001, the group has released twelve Cantonese studio albums, four Mandarin studio albums, three extended plays, five compilation albums and four live albums. Most of their singles reached the top of many musical charts.
