Dressed in spaceman like silvery suits, Hong Kong singer and actress Kelly Chen is working on the music video for her new song titled "sometimes lonely".

The new song matches the life philosophy of the star, who said she enjoys private times very much, according to a report by Tungstar on Thursday.

Chen will hold a solo concert in Hong Kong in June. To perfect the stage effect, the producing team has imported eight advanced projector equipment from Australia and is planning to build a five-floor tall screen.
