HONG KONG: Singer Calvin Choy of Cantopop trio Grasshopper has amused netizens after a photograph showing him with six fingers on his right hand was mistaken for an artificial intelligence (AI) glitch.

The 61-year-old singer caught people's attention after appearing in the TVB drama This City Never Sleeps, which also stars Julian Cheung and Ron Ng, according to 8Days.

A netizen shared a screenshot of Choy on Threads, suggesting the image was AI-generated because of his unusually shaped right hand.

"You can tell this picture is AI-generated just by looking at his right hand," the netizen wrote.
