Justin Bieber used his appearance as a guest mentor on The X Factor USA to show the world his own talents, performing a cover of The Beatles 'Let It Be whilst playing the piano.
Bieber delivers the song with a healthy dose of serious-face, emoting for his life as he runs through The Beatles classic hit whilst LA Reid watches on.
X Factor USA continues to pull out all the stops in a bid to attract viewers, with Bieber joining LA Reid for the Judges Houses stage of the competition. It is not known who will assist fellow judges Demi Lovato, Simon Cowell and Britney Spears in their search. Something tells us Sinitta won't cut it this year.
Meanwhile, Bieber recently hit the headlines after being sick whilst in the middle of a concert last week. He later blamed the bout of illness on drinking too much milk prior to walking on stage.
