It is not easy to practise love. Man of the moment JJ Lin learned that the hard way when fans laughed at his slip-up during his concert in Huangshi, China on March 30.
The Singaporean Mandopop superstar was passionately belting his hit ballad Practise Love when he suddenly forgot the lyrics.
The flustered look of the singer was captured on the giant display, sending the whole stadium into laughter.
Luckily for those of us who weren't there, the hilarious moment was captured on video by an audience member and soon went viral on Chinese microblogging site Weibo.
Amassing over 11 million views and 13,000 shares as of this article, the hashtag "JJ Lin messes up during concert" became a trending topic.
Fans were quick to poke fun at the singer's embarrassment, especially since the song is a slow ballad.
Users made fun at the way he tried to hide his mistake, and some even gave him tips to recover from his next mess-up.
"The next time you forget the lyrics, just point the microphone at the audience and they will help you sing that part," read a comment on Weibo.
Another comment turned the tables, arguing that if JJ didn't make any mistake, given his well-known vocal prowess, the audience might think he was lip-syncing to the song's recording.
JJ's Sanctuary World Tour is currently in China, with Suzhou the next stop tomorrow (April 6).
Recently, the 38-year-old celebrated his birthday with longtime pal Stefanie Sun after she dropped by his studio to surprise him with a cake.
