January 09, 2021 Instagram/ zaiwang107 Ex-Mediacorp actor Jeff Wang had jaw surgery and liquid diet for 4 months afterwards If you think actor Jeff Wang — the overall male champion of Star Search Singapore 1999 — looks somewhat different now, you're right, he went under the knife. In a recent interview with Taiwanese media, the former Mediacorp actor — who is based in Taiwan now — said he had jaw surgery to correct a bite problem. It was not mentioned when he had it. The 44-year-old admitted he still shudders in fear thinking back on the surgery. He had to sign a medical indemnity form prior to surgery as there was a risk of permanent paralysis in his mouth in the future.
