Jackie Chan Hiu-ki, also known as Kellyjackie, is a Hong Kong pop singer and a former member of a band called the Royals.

[1] In January 2005, she wrote the song He invites me to Disneyland (他約我去迪士尼) to cope with the stress of the Hong Kong Certificate of Education Examination.

Many were amazed by her talent, given her age and her busy schedule as a secondary school student preparing for her O-level exams.

Nevertheless, the song eventually became extremely popular and received widely positive reviews in Hong Kong, Macau, and Guangdong and landed her a 5-year recording contract.

After a 5-year hiatus from the Hong Kong music scene because of contract problems with her former manager, she made her comeback by signing with MusicNEXT in 2011 for 3 years.
