Justin Bieber's cameo in The Simpsons has hit screens in the US.

As previously reported, an image of the Canadian immortalised on the popular animated series recently emerged online ahead of the episode's air date.

Bieber's cameo in the program was shown last night (May 12) - but it only lasted mere seconds.

The audience was also jokingly warned ahead of the singer's appearance, with a subtitle reading:

"Thirty seconds to Justin Bieber - you may start or stop watching according to your beliefs."

The cameo saw the 19-year-old turned away from a local talent contest, with the 'Believe' star annoyed that he wouldn't be able to win the $25 prize. Watch Justin Bieber on The Simpsons below:
