The 'Under The Mistletoe' star performs a festive duet with the 'Superstitious' singer on FOX's reality show finale.

Justin Bieber has said it was his "honour" to perform with Stevie Wonder on The X Factor USA live final last night (22nd December).

The 'Baby' singer performed 'The Christmas Song (Chestnuts Roasting On An Open Fire) during yesterday's show and was joined on stage halfway through by the iconic singer for a duet.

"We went real BIG on X factor 2nite," Justin tweeted after the event. "Thank you to the legendary STEVIE WONDER."

After being asked by The X Factor USA host Steve Jones how the unlikely duet came about Justin said Stevie was simply returning the favour.

"I actually got the honour to perform at his benefit, so he was gracious enough to come out and perform with me and it was an honour and I just want to say now, "Stevie you're one of my idols so just the fact that you'd come out and do this is an honour so thank you."

Stevie himself said the performance had been "fun" and described the 'Under The Mistletoe singers as "incredible".

He added: [Justin] reminds me of myself when I was a little boy."

Justin went on to sing a cover of 'Santa Claus Is Comin' To Town' during which he was joined on stage by finalist Drew Ryniewicz.

The X Factor USA final also saw appearances from Leona Lewis and 40 Cent, following which Melanie Amaro was crowned winner of the show's first series.
