Twins members Gillian Chung and Charlene Choi appeared to be quite intimate again as they reunited for a lighthearted video greeting to famed Hong Kong cinematographer Wing Shya, who has joined hands with screenwriter Tony Chan for the romantic comedy "Hot Summer Days."

This marked the first cooperation for Twins after its split in 2007 in the wake of member Gillian Chung's involvement in a nude photo scandal.

Reportedly, Charlene Choi also made a guest appearance in the star-studded film, which is slated to hit cinemas on February 11.
