Bernice Liu, Belinda Hamnett and Joyce Tang were filming a commerical and between takes were joking around. Because of Belinda, Bernice got all her Catonese mixed up.
When the 3 ladies Bernice, Joyce and Belinda were on set it was thought that the 3 would compete to be the sexiest but Joyce and Belinda were laughing at Bernice who is the endorsement star was rather covered. Bernice said, In the ad I play a doctor so I cannot reveal anything. Now you can steal the camera!" And while shooting the ad the 3 ladies looked rather professional and serious but once the shooting stopped all 3 were laughing and talking loudly joking with each other.
