Twins is a Hong Kong-based female Cantopop duo created in the summer of 2001 by Emperor Entertainment Group (EEG). Twins is made up of two girls, Charlene Choi Cheuk-Yin and Gillian Chung Yan-Tung.
Charlene Choi was born in Vancouver, Canada on November 22, 1982. Gillian Chung was born in Hong Kong on January 21, 1981. Before signing with Emperor Entertainment Group, Chung studied at Royal Melbourne Institute of Technology in Melbourne, Australia. Chung had also worked as a part-time model during one of her summer vacations in Hong Kong.
Similar to Chung, Choi was also a part-time model who had appeared in several advertisements. She became famous after her participation in the television program Y2K, organised by Radio Television Hong Kong (RTHK).
Both Choi and Chung caught the attention of EEG manager Mani . In one of the episode of Be My Guest, Mani was interviewed exclusively about the discovery of Twins. She talked about how it was fate that helped her select the two singers out of a catalog of thousands of potential young candidates. They subsequently auditioned for and later formed the duo known as Twins.
