It would appear Jay Chou and JJ Lin are enjoying each other's company greatly, while purportedly filming for a variety show.
First they were spotted at Sim Lim Square.
Then they were seen at Madame Tussauds fooling around together.
Now, they are doing what they do best.
Duet performance
Previously, both Chou and Lin had performed together almost a year ago at a concert in Taiwan.
Now, according to three videos in an Instagram story uploaded by user peggyonggg, it appears both singers decided to belt out another duet together allegedly on Sept. 12, to the tune of a song by JJ Lin titled 手心的薔薇 (Beautiful in English).
The location of their performance was at Voice Art Karaoke Lounge at Bishan which is owned by JJ Lin's parents.
In any case, it's clear that they are having a good time.
