The 'Mistletoe' star shows off his impressive rap skills with a freestyle performance.
Justin Bieber has performed a freestyle rap over Kanye West and Jay-Z's recent single, 'Otis'.
The 17-year-old singer delivered the performance live during an appearance on a US radio station earlier this week.
Wearing a trilby hat, Justin rapped for nearly two minutes and referenced his fans, dreams and incredible rise to fame during the freestyle.
In one line, he said: "There's a bigger me inside this little me, screaming out: I should make history."
Justin's rap, which you can watch below, comes in the same week that the star released his Christmas album, 'Under The Mistletoe'.
The LP features collaborations with Usher, Mariah Carey and Boyz II Men.
