Justin Bieber learnt this the hard way during a performance at 1OAK in New York City on May 23.
He was singing his latest hit “Despacito” with The Chainsmokers but when he got to the chorus, he was unable to sing the Spanish lyrics live so he sang “blah blah blah dada dada blah” instead.
As the performance was getting from bad to worse, he decided to take the easy way out and held the microphone to the crowd to let them take over.
Thankfully for us, the hilar footage was captured by TMZ along with a bunch of sneaky fans.
