WATCH: Singer exposed when she lip-syncs into wrong end of mic

A Chinese folk singer was caught on camera lip-synching during a live performance on national TV when she held her mic upside down.

Sa Dingding, who was performing at the Lantern Festival Gala in China, quickly realised her mistake and flipped the mic over - but not before it was caught on camera, Mashable reported.

The singer later joked on her Weibo account that she'll sharpen her acting skills 'next time'.
