Justin Bieber might want to swot up on the lyrics to his new track Despacito.

Justin seemingly forgot the Spanish lyrics to his own chart topping single during a performance in New York on Tuesday night.

The singer launched into the track, with Luis Fonsi and Daddy Yankee, but appeared to fudge it part way through.

He got around the awkward situation by making up some new lyrics, namely 'blah, blah, blah, blah, blah'.

He also changed another lyric to 'I quit smoking ciggies'.

Now in Bieber's defence, we can totally relate to making stuff up to our favourite songs when our minds go blank.

He clearly feeling a lot better since he (over)shared with his fans that he had conjunctivitis, posting a total of five Instagram pictures as proof.

Justin is heading to UK shores in the summer as he headlines British Summer Time Festival at Hyde Park on July 2.
