Justin Bieber might be the most popular solo artist in the world right now, but that doesn't mean that he's "perfect" as the teen has admitted to using vocal-tuning software for his voice.
The 'Boyfriend' star insists that he doesn't use Auto-Tune, because he favours another form of software which he believes that nearly every artist will use.
In an interview with Q magazine, he said: "I don't use Auto-Tune. They tune my vocals - they use Melodyne. But every artist uses Melodyne. Not every artist, but 99 per cent of artists. I like the sound, the perfectness of tuning in the record. No one has completely perfect pitch."
Justin Bieber is currently promoting his new album Believe and he stopped by the Tonight Show with Jay Leno in New York last week, but not before he surprised waiting fans with an acoustic performance.
Bet he didn't have his Melodyne then!
