What do you say after 18 years of going through both good and bad times together as Cantopop duo Twins? No wonder Charlene Choi found it hard to tell Gillian Chung, 37, who married Mr Michael Lai, a doctor, in Los Angeles last Friday, how she felt. In her Instagram post, Choi, 35, wrote: "I write it down, I erase it. After erasing it, I write it down again, multiple times. No matter what I write, I just couldn't write out how I really felt... Although you are no longer Mrs Choi and now Mrs Lai, you will always, always be my Little Gill Gill." Chung's bridesmaids were (from left) Yumiko Cheng, Joey Yung and Charlene Choi.
